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.

Notes -
In my latest essay, I try to list the major points I'm aware of that puncture the progressive narrative on economics, without trying to directly touch on the Culture War's social fronts.
Reality Has a Poorly Recognized Classical Liberal Bias
I think most people here have enough exposure to libertarianism that they are at least aware of these issues (even if they don't agree with them). If you think I missed one or I'm somehow dead wrong please do indicate so.
that is a small aside - but large reason for that is that USA is much hotter and until recently it would be not-so-needed
article you linked even mentions it
Well, yes. That was true of much of the northern U.S. until more recent times.
The problem is that the Europeans can't quite seem to get AC now that they probably ought to have it. It's kind of banned in many places.
That is a citation needed moment. Source - I am from Europe. AC is quite popular and widespread. And treated as necessity during summer. We just don't try to achieve polar temperatures and usually put it to 20-22 C (don't ask me why AC units became such pussies lately)
I have been assured by top conspiracist minds that the refrigerant chemical companies ensure their regulatorily captured lawmakers’ outlaw refrigerants as soon as they go out of patent, purely for environmental reasons of course.
From a purely physical/technical perspective, modern refrigerants are fine.
Even refrigerants that completely satisfy our modem sensibilities (low global warming potential, zero ozone depletion potential) work as well as they always did. There's no magic sauce in those old fluorocarbons. Hell, even propane and CO2 are basically ideal refrigerants (but require a complete redesign of the cooling circuit, with much beefier parts to allow for much higher pressures).
If legacy AC systems seem to have more power, I'd assume they come with a more powerful compressor, and without pesky electronics that limit that power in any way.
Part of the magic sauce is that they work at lower pressures. Other magic things include that they don't form HF if there's any water in the system, they're compatible with less expensive non-hygroscopic (remember that HF?) oils, they're single component so there's no need to replace all the refrigerant if there's a leak, and the very fact that the environmentalists hate them most makes them cool better. OK, maybe the last one is a myth.
Propane runs fine in a system designed for R-12. The issue with it is flammability.
While propane's flammability makes repairing systems using it more dangerous, it doesn't make much difference in running the system. It's a significantly better refrigerant than r-134a(the main thing it's replacing now) or r-410a(which, along with 404, it's likely to displace a lot of in the coming years) but a slightly worse one with similar drawbacks to r22(which has been banned/in phaseout for a while).
