For some reason people think that cartoons are better if they have pointy chins, high pitched voices and unnatural hair colors. I have concluded that no matter how weird you make your characters look, they're still stupid. So, in theory, if you switched the style of anime with the style of NORMAL cartoons, people would say it sucked. Therefore, it can be concluded that the attraction does not lie within storyline (another way you can prove this statement is because most anime is either about guys with EXTREMLY stupid super powers of getting raped by tentacle monsters). This can only mean one thing. The Japanese have mastered the arts of hypnosis and are grasping the minds of people. We all knew the Japanese were up to something, but what was unknown to us was that they've already gotten started. The Japanese have a hold on our population through their hypnotic art powers. Those of you who disagree are under their command. I wish I was kidding.
My second theory is that kids are just poseurs. Have you noticed that there are kids of all ethnicities are under the influence of anime? Well, that is, all of them except ONE. There are almost no Asian males I know of who watch anime. Yes, the target audience of anime doesn't even like it. However, all non-Japanese are attracted to it because they wish they were Japanese. This fact also fits in with theory number one. The Japanese are trying to manipulate every ethnicity EXCEPT their own. Either way you look at it, it makes sense.
Naturally, theory number three is because people are pure fucking stupid. Go figure, what else have I said on this website.
