Agreed. "old-fashoned" nude magazines probably are bad for you, but not that bad; while having the whole Internet where you can always some more degenerate shit probably fucks you up immensely.
A modern problem is also people being terminally online and never leaving their rooms, only talking to people in your bubble. Back before the Internet, you'd get exposed to opposing views, other hobbies, such things. Now if you're into Warhammer as a teenager, you'll start talking to people only about Warhammer. This is probably why every zoomer has autism-like hyperfixations.
Also zoomers are taught repeatedly that they're "special". And if you don't feel as special as you're taught you should, you find something that makes you feel special. Which now is being a tranny or a fag. Once you just tell people that you're a fag or tranny, you're suddenly bombarded with attention.
