Can anyone provide any actual evidence that says this kind of thing makes children's lives worse? I was pretty uncensored as a kid and I'm honestly really grateful for it, i feel like it helped me adjust to the adult world well before my peers.

Honestly the things that got to me as a kid more than anything else was violence and the news. I recognized stuff like family guy to be fake and silly, but seeing and hearing about people getting killed or severely hurt in media and the news was sometimes traumatizing.
