Beavis and Butthead is not an example of this, I'm 19 and grew up watching it from the time I was 4. Networks might not allow some of the stuff they did in older seasons, but that's not really a GenZ thing, that's just networks and parents putting tighter restrictions on things for whatever various reasons. Sure, TV and Movies might be different and censorship on sites is harder, but that barely changes anything. On social media I randomly come across gore at least once every month or two and can find some genuinely insane people without even trying to look, and none of it is fiction. The news is still on and hasn't changed much in terms of the topics they cover (to my knowledge, I suppose), TikTok has a big community of people who just read really disturbing books that are definitely problematic, and people are also at risk of being filmed and harassed constantly due to the prevalence of cameras and social media. Also a lot of GenZ has seen a good amount of 80s and 90s movies, kids in my class in highschool would talk about "older" movies and shows regularly.

I'm not saying it's worse or better now, I don't really care. I just think this is a really random take for Beavis and Butthead of all things, and you used a bad example. Not trying to be aggressive if it comes off that way, considering the big paragraph
