One reason is the explicit sex in books pushed for minor schoolchildren, that's new.
which books? and be careful, because I'll bring bugs bunnie who often dressed in drag, or tom and jerry same thing. those were the things I grew up with. and we laughed back then.
edit: see the irony
edit2: see the sex innuendo, guys whistling at a drag queen. back then we laughed and thought it was funny. I think most of those cartoon were made before or around when i was a young kid. I thought it was funny. but now, hell no, their indoctrinating my great great great grandchildren. I find that ironic. when we grew up with this.
