Um I hate to say this but why does everybody think that American little kids are unmature and uneducated brats? I have a little 2 year old nephew that understands the reasons behind "why grandmum passed away."
When I was 2 years old people died, they didn't pass away. I think America's mass use of Euphemisms might count as uneducated.
Also in the reason for no school shootings in Japan, to my knowledge, is that bullying is stopped over there as soon as possible. UNLIKE THE DAMN AMERICAN PUBLIC SCHOOL SYSTEM!
Might be something to do with the lack of right to bear (and hence buy) arms. I'm all for bashing the American school system, American children, etc. But let's not forget that the law makes it easier.
Back on topic, even if it is watched a lot, Adult Swim is not as popular as Toonami. Besides, think about it this way. If people have only seen cut down versions on Toonami, that increases the incentive to buy the uncut DVDs. Just like the European who pirates the American game claiming "Why should I wait 2 months to buy the exact same thing?", people would rather download Adult Swim TV rips than wait for DVDs.
