Culture War Roundup for the week of March 2, 2026

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.

Chemical rockets do a lot better in the worst case scenario for a rocket launch.

I agree that they’re too weak for the real extrasolar timelines.

If there was a bunch of fissile material sitting around in the asteroid belt, maybe that would be a good reason to get up there. Unfortunately, a cursory search tells me that it only got concentrated on Earth by some sort of geological distillation. Probably not available outside of gravity wells.

Fissile material is extremely valuable per unit mass, and we're never going to run out of it on Earth, so you wouldn't save much by farming it out of the gravity well. What WOULD be valuable is mining and smelting a large amount of metal or rock that you can use to build large structures in space.

I don't see why we should be worried about a little fallout in the atmosphere, we detonated thousands of H-bombs and there were no significant radiological consequences. Millions of people die every year from air pollution already.

Wait for fusion IMO.

The risk isn't from a nuclear explosion, it's from an explosion that scatters nuclear material which is way more likely in a rocket than a bomb.

Er, yes, that's what "fallout" means. You missed @RandomRanger's point. One rocket's worth of nuclear material in the atmosphere is barely a blip. Note that even a normal rocket is chock-full of toxic chemicals, which is why we don't launch near population centers. Most normies tend to be off by many orders of magnitude when they intuit how dangerous "nucular" things are.
