This weekly roundup thread is intended for all culture war posts. 'Culture war' is vaguely defined, but it basically means controversial issues that fall along set tribal lines. Arguments over culture war issues generate a lot of heat and little light, and few deeply entrenched people ever change their minds. This thread is for voicing opinions and analyzing the state of the discussion while trying to optimize for light over heat.
Optimistically, we think that engaging with people you disagree with is worth your time, and so is being nice! Pessimistically, there are many dynamics that can lead discussions on Culture War topics to become unproductive. There's a human tendency to divide along tribal lines, praising your ingroup and vilifying your outgroup - and if you think you find it easy to criticize your ingroup, then it may be that your outgroup is not who you think it is. Extremists with opposing positions can feed off each other, highlighting each other's worst points to justify their own angry rhetoric, which becomes in turn a new example of bad behavior for the other side to highlight.
We would like to avoid these negative dynamics. Accordingly, we ask that you do not use this thread for waging the Culture War. Examples of waging the Culture War:
-
Shaming.
-
Attempting to 'build consensus' or enforce ideological conformity.
-
Making sweeping generalizations to vilify a group you dislike.
-
Recruiting for a cause.
-
Posting links that could be summarized as 'Boo outgroup!' Basically, if your content is 'Can you believe what Those People did this week?' then you should either refrain from posting, or do some very patient work to contextualize and/or steel-man the relevant viewpoint.
In general, you should argue to understand, not to win. This thread is not territory to be claimed by one group or another; indeed, the aim is to have many different viewpoints represented here. Thus, we also ask that you follow some guidelines:
-
Speak plainly. Avoid sarcasm and mockery. When disagreeing with someone, state your objections explicitly.
-
Be as precise and charitable as you can. Don't paraphrase unflatteringly.
-
Don't imply that someone said something they did not say, even if you think it follows from what they said.
-
Write like everyone is reading and you want them to be included in the discussion.
On an ad hoc basis, the mods will try to compile a list of the best posts/comments from the previous week, posted in Quality Contribution threads and archived at /r/TheThread. You may nominate a comment for this list by clicking on 'report' at the bottom of the post and typing 'Actually a quality contribution' as the report reason.

Big week for nuclear power in Ontario
After France, I believe Ontario is the king of nuclear power generation: roughly 60% of the province's electricity is generated from its nuclear power plants. However there were growing issues: cost overruns and increased political opposition in the 1980s had prevented development of new reactors for decades, and the legal battles over just the initial environmental assessments of an attempt to build new reactors at the Darlington site beginning in 2006 meant the project ended up stillborn (the provincial government abandoned it in 2011, and the court scuffles went on for another five years past that). After that successive Liberal and Progressive Conservative governments were plenty happy to kick the can down the road: after all, getting new hydro or nuclear generation going is never something that's going to come online in time for next election, so it just all disappears beyond the political event horizon. Never mind the various projections anticipating a large and growing gap between generation and demand, a gap probably understated if electrification of heating/transport accelerates.
Then all of a sudden it becomes an issue because one of the major nuclear plants (Pickering) is all of a sudden due for retirement before the next election, and there's a mad scramble to fix things. But at least the positive is that it appears to have finally shaken decision-makers out of their reverie: 4,800 MW of new reactors at Bruce Power will see it reclaim its former status as the world's largest nuclear plant, and three new small modular reactors will add 1,200 MW more. The scale is considerable: just the three new SMRs will generate more electricity than Canada's ten largest windfarms combined.
And so far the response has been positive! Looking at Reddit comments might not necessarily be instructive of the general reaction but it's been nothing but relief so far. I've been scanning left-leaning legacy media (there isn't much left in Canada) and what criticism there has been so far has been mainly tepid concerns about cost (which are valid, controlling cost overruns are pretty important here).
It'll be interesting to see the federal response here. The current Minister of Environment, Steven Guilbeault, is a former Greenpeace guy and has been vocally anti-nuclear in the past. The regulatory hurdles these projects will have to mount are mainly federal and there is the potential for some kind of obstruction. On the other hand the current Trudeau government has been cautiously open, at least rhetorically, to new nuclear development and has been helping fund SMR development. We shall see how it pans out. In general public sentiment isn't an issue: the large majority of Ontario's population already lives close to a nuclear power plant and public support is high. The concern is how interest groups or specific influential individuals might use the legal system or regulatory requirements to kill by a thousand cuts.
I'm going to take this chance to indulge in just a little bit of optimism!
one thing that I've always found interesting is that the thing that tends to unite the internet is a very pro-nuclear power stance. reddit, twitter, themotte, hell even rdrama, are from what i can tell, decidedly pro-nuclear power. it's an interesting trend that i've seen that has had quite large staying power. it's hard to argue that reddit for example has the same general politics as it does 10 years ago, but even then the issue of nuclear power seems to be constant.
i'm sure there are some small groups that are anti-nuclear on the internet, but i think you'd be more hard pressed to find anti-nuclear communities online than to find a lot of different things. i find that observation to be pretty interesting.
i'd argue this is for good reason: nuclear power seems to be an amazing way to generate base load, tends to emit less radiation than coal powered plants1, and is dozens or hundreds of times cleaner than other energy sources.
1: the study i linked found that for the energy generated, more radiation is given out by fly ash, which contains trace amounts of uranium and thorium. while the amount of radiation that makes it into people from both of these sources isn't dangerous, it's worth pointing out when given the concerns of "gonna be irradiated."
The title of that article is laughably false. The underlying point it is based on, that under normal operation a nuclear plant releases less radioactive material into the environment than a coal plant, is technically true but grossly misleading. Under normal operation nuclear plants release essentially no radioactive material, the radioactivity concern is concentrated purely into the possibility of something going wrong. Sanity-check I did after encountering this argument a decade ago:
This doesn't mean that nuclear power is overall a bad idea, but it's definitely not because coal is a worse radioactivity concern. From what I've heard this particular misleading talking point has been going around even before it started circulating on the internet, I remember someone telling me that it was going around Stanford decades ago. People should be cautious with counterintuitive factoids like this, because often they spread because they are too good to check.
I addressed this in the footnote.
It is a quite common myth that living near a nuclear power plant emits radiation during ongoing operations.
But it's not true that "for the energy generated, more radiation is given out by fly ash". You didn't say "so long as nothing goes wrong", so the average amount of radiation released per energy produced includes the risk of disaster. And since nuclear power plants involve significantly radioactive material and coal plants don't, even a tiny risk is enough to push the average way above coal plants. The fact that Fukushima alone released more radioactivity than the fly ash we would get from burning all coal deposits on Earth makes this clear.
Then just say "nuclear power plants release virtually no radiation under normal operation". Don't try to make it sound like nuclear beats coal in terms of radiation, on a technicality sufficiently narrow that both you and the Scientific American article you link (and the people I've seen bring up this talking point before) stumble into outright falsehood. Nuclear beats coal on plenty of metrics, there is no need to compare them in terms of radioactivity besides the appeal of being counterintuitive.
