I think it used to be a little more dramatic than it is now. I cannot stand guys who post things that they would never dream of saying to me in person. The road section was the worst and I got in arguments all the time, I even stopped posting there for a couple of years. There was another reason as well but I won't get into that.
Now when someone gives me a punk ass comment or the politically obsessed tries to get political I don't even reply, I just put them on ignore and make them go away forever. I have 24 on the list right now.
