I got over this by slowly growing up, not by having a crowd tell me I was an ass. I think if the crowd had pressured me back then, I'd tell them to go jump in a lake.
These guys were wrong, no two ways about it. My concern is that we've created a system where kids can't go out and get drunk, make racy comments about girls -- basically act like kids -- without the entire world coming down on their head. Everything you do online lasts forever. That doesn't sound like a good thing at all.
