^ I feel like it can be a plethora of reasons with the anime thing. I have seen enough anime that have overly weird (sometimes to the point of awkward or disturbing) concepts/characters/themes/plot points and nothing is really done about it in the shows, so I think when you have certain things that are extremely weird and normalized in the anime, people who ARE already creeps themselves see it and cling onto certain animes because they see themselves being portrayed as normal or funny in these shows, so they probably think it's way more okay to be unhinged in anime spaces because of that (like with yandere or the perverted characters. If there's an already mentally unsound individual seeing these characters being portrayed as cool or normal, they'll most likely be most comfortable being that thing in anime conventions/places because the community 'accepts' those behaviors for the most part). That being said, I think it's ultimately up to the consumers watching and not the anime itself inherently. I am a firm believer though that a lot of animators over their in Japan/Manga writers have their own mental issues too, especially with the Loli and Shota characters, because that IS full blown pedophilia/creepy behavior for you to have the unmitigated gall to even write a show where children are having full blown sex (with an adult OR another child). But again, it's also up to the consumer to not consume certain content and feed into that. But, if you are already: 1. A creep, 2. Mentally unwell (not in a creepy way) or 3. Struggling with certain things (thoughts, behaviors and desires), then you will most likely gravitate towards an anime that feeds into your present struggles in the first place. What I'm getting to is that like with any form of content/media there's going to be good and bad people/spaces as well as shows. I do believe there are plenty of healthy and good anime consumers out there, but with practically much of everything, usually the bad side(s) end up being pushed so that's the only thing you end up seeing.
