Also, my past lives from their view would probably just scream "sadism caused by repressed weakness", they wouldn't be able to imagine something else, because to them everything they do is motivated by denying, repressing or fleeing from something. They can't think someone is just naturally sadistic for no reason or just think it's genuinely funny, they can't see the simple fun in things.

There is a difference between trying to be edgy in gore threads or constantly making a point of how sick one is, or self identifying as a pedo and telling everyone about it for effect, vs just doing any of those things and not thinking anything of it.

The people with repressed trauma or fetishes just have to tell everyone how "sick in the head" they are for not following society's values. A mild variant of this being 8/u/ where they kept making an (annoying) point out of how their lesbian fetish was not in line with society by calling it "forbidden love"; they're not after yuri itself, but the "forbidden" aspect.

Me, I don't care about allowed or not because I don't care about other people or any values they have, if I like something I like it and I'm not interested in telling anyone about how it's different from what someone else thinks is right, unless they try to somehow stop me from doing what I like. That's the only part that matters imo, I want it to be ignored, not specifically advocated as special, as forbidden or as exclusive access natured, the important part is the quality in itself.
