Usually people who hate you try to discredit your argument by making you appear weak and stupid. For instance, you can tell some story about some person you met and they might say, "Oh, did he also say you suck LOL?". 
They definitely like to use the "suck" word a lot, to disrespect you, and discredit your argument. Even if they see you talking to another person, they will mutter, "This guy sucks.", loud enough to where you can hear it.
Of course, when your annonymous on the net you don't hear it as much, but if your on some place where people know who you are, and they don't like your internet message, then soon you will soon be insulting you.
Anyhow, it's not hard to see why prison and school can often be a battleground to gain respect, as bullies are there to rip you to shreds. 
Often they're motivated by jealousy, as any display of anything interesting will motivate an insult session.
Anyhow, two can play the game, not just radical athiests. If you insult a lot of religious people, some of them will try soft terrorism on you.
