This really sounds like evidence for my claim, that what you're saying is based on your feelings towards that community.

The point of that story is to make technical concepts more accessible and easier to ingest [0], not necessarily to make a point by itself. Framing it as a weird fantasy is disingenuous.

This is again, feelings presented as evidence. The fallacy of appealing to emotion ("It must be false because it feels wrong"). Thought experiments are primarily meant to provoke thought, not as reliable predictions of reality. People are free to indicate where any thought experiment is lacking using well reasoned arguments. "It feels wrong" can be a great start for that, but never a good end.
It's not presented as evidence. I was going for the "basis" part of your ask for evidence/basis, which is definitionally looser: elaborating on my thoughts and the kind of content I've seen that made me think this.
Let me put it this way: I have spent hundred of hours reading rationalist and rationalist-adjacent posts on LessWrong, SSC, HN, Reddit; the entirety of HPMOR, a decade ago; books like Superintelligence, The Age of Em; the LessWrong IRC channel, a while back; I have reasoned arguments about pretty much all of it, including the stuff I consider to be ungrounded. What I don't have is an entire day to collect the material and lay it all out to you in a 5000 word dissertation. Do you see what I mean?
So, yeah, it's a "feeling" -- it's the "feeling" I ended up with after spending all that time engaging with the material, thinking and arguing with people, which is why I trust it -- I have worked very hard to develop this intuition. And perhaps I could pull from it to craft an argument you would find compelling, with all the necessary receipts... but you must understand that this would be a massive time sink and I'm not going to do it. It's not a reasonable ask in the context of an HN thread. To a point you just have to trust me, or not trust me on this. I don't expect you to. It's fine! Not every thread can have a conclusion.
> People are free to indicate where any thought experiment is lacking using well reasoned arguments. "It feels wrong" can be a great start for that, but never a good end.
It's triage. The better your intuition is about whether an idea will lead somewhere, the less time you will spend pursuing dead ends. In an ideal world, you dismiss thought experiments will well-reasoned arguments, but the reality is that there is an opportunity cost to it. Using "feelings" to end some conversations is unfortunately a pragmatic necessity.
> To a point you just have to trust me, or not trust me on this. I don't expect you to. It's fine! Not every thread can have a conclusion.
It's clear how you got to your opinions. I see no reason why anyone that did not already share them would do after your comments, though. Some examples or bits of evidence would have worked towards convincing readers.
> but the reality is that there is an opportunity cost to it. Using "feelings" to end some conversations is unfortunately a pragmatic necessity.
The latter is something completely different than dismissing thought experiments based on feelings after having "pondered" and tried to rationally dismiss them. One of the key tenets of rationalism is exactly that feelings and intuition can be incredibly misleading. It's fine to have them and see value in them, but thinking they are reliable when you cannot rationally support them is nothing more than gambling.
