You don't have to bring up those bullying cases. They're terrible, but what I criticized about your posts was that nothing in there comes close to Rudy's case. The verbal abuse? The permanent ostracizing? Yeah, I know that from my own school past. What I've never heard of is stripping a student naked and pinning him in a spot to humiliate him. That's why I said the anime overdid it there. If something like that happens more than just once irl, then I'll take back my criticism.
That Japan has a problem with bullying is not news. Although while it might be somewhat worse, bullying is a huge problem anywhere in the world, even if the media doesn't make it the big news it deserves.
