Yeah, I don't understand why people think metalheads are violent. Sure, there may be a couple of violent metalheads, but there are some violent people in every kind of genre of music. Some weeks ago I've been to a concert and the people there were some of the nicest I've ever met. Normally I'm not that type of person who talks to strangers, but the people there all were really friendly and we had some awesome conversations about our favourite bands. And all metalheads I met on the internet were pretty chill people too.
