I used to enjoy conspiracy theories, because I thought it would be cool if they were true.
Things like cryptids, aliens, etc...
But now all the conspiracy groups are filled with stupid right-wing science deniers.
Same. I have always loved it as a fictional genre, and as a fun sort of "what if" form of escapism for life in general. We've pretty much taken all the mystery out of the world, so that kind of stuff filled that void for me for a long time. But then it turned into a pipeline to recruit people into right-wing paranoia, and now I can't really enjoy it anymore.
