I've been showing a couple of episodes and Grand Battle Rush to my brother, He thinks the series is really cool now! I've also shown him that video on YouTube which compares the dub and sub side by side, and he also realizes why we hate 4kids.
Notice, that just like in the US, teen violence in Japan really has nothing to do with cartoons and video games. XD It almost always goes back to parenting.
WORD!!!
EDIT: Oh, and I was reading a little bit back to where there was some small talk about shootings. Another factor there is that Japan has very strict gun control laws.
