I guess the rest of the people acting like bullying behavior is acceptable were bullies from the start then. I'm not sure which is worse.
Well adjusted people find bullying behavior unacceptable regardless of their social graces now or in the past. Many of us grew past it or rejected it at an early age but there are some for whom it is a lifestyle. Empowered by the protection of the keyboard (greater internet fuckwad theory). It is a behavior we as a society will have to deal with eventually. Maybe the kids who grew up online will do better but sadly I doubt it.
