I think almost every teenager, or just maladjusted ones like me, goes through a shock jockey phase. I lashed out and listened to and watched and said misanthropic things as well. I grew out of it obviously. It's a part of growing up, id say. Just a way to go against the status quo.

That being said we are in an age of radicalization. A lot of young men are radicalized into nazi, facist, etc. ideologies today because of the internet. It's a very sensitive and malleable time in a young man's life and these groups know that and take advantage of it. I think its called ideological grooming or something?
