The boards do have bigots and trolls -- but just look at how people with integrity behave around such people and you find that they have a different purpose on the forums and so, they attract a different type of crowd. You find that they don't get caught up in all the drama because they are there to discuss issues instead of talking about people all the time. Where as with bigots and trolls, it's the complete opposite -- they talk about nothing but people since they have no knowledge of any subject. Also a reflection of low intelligence as well.
Take a look at Vince as a perfect example -- How does Vince react when he comes across a troll that accuses him of being a self-centered know-it-all 'conspiracy theory' tool that thinks he's better and smarter than everyone else? Or a troll that always makes stuff up about a 7 year work history. Do you see Vince getting angry, lashing out or losing it? Does Vince then go back to the board using 900 different daily names to get revenge? Does he chase the person around from forum to forum?
No -- and what you discover is that the bigot that makes these kinds of 'ad hominem' attacks is often left there by himself as Vince walks away and blows them a cyber-fart. Because, that is how people of intelligence and integrity act. They respond to things of value, rather than idiots that are trying to provoke a response and get you to defend yourself from 3rd grade insults. Vince would have to sink down to that level of immaturity just to acknowledge it. And that's why you see people like Vince, Mondo or JVH, never get caught up with drama and why biogts and trolls never can shake them up. They are operating from a level that the emotionally immature troll cannot even comprehend.
