Haven't watched the videos, but based on the quotes they don't sound weirder than actual children's cartoons like Invader Zim or... actually, Invader Zim is such a good example that I don't think I need any others. All of those quotes would fit right in on Invader Zim (which is on the dark end of children's cartoons but is a children's cartoon nonetheless). Children's cartoons are wacky. I agree with the commenters who say you're jumping to a conclusion.

I've had some success discussing the "animation is not just for kids" issue by linking people to TVTropes' article on the Animation Age Ghetto. A parent might want to read What Do You Mean, It's Not For Kids?.

Here's an issue I'm much more curious about: I have a friend who hates animation, and I don't think I can change her mind about this. To hear her tell it, she basically can't respond emotionally to animation - can't empathize with animated characters, etc. I wouldn't have thought this was possible. Does anyone know anything about this kind of phenomenon?
