I think generally no. Most people fool themselves into thinking they're nicer than they really are to begin with, but the internet, and most especially forums, really do make it much harder to tell when you're coming across to others as a complete asshole.
Certainly there are genuinely horrible people that have just learned to hide it in reality but don't bother on the internet, but I think most of the time it's simply people not realizing how serious they seem or especially that everyone else probably has the same problem and they're really not actually horrible assholes, they just seem that way because forums are an inherently flawed method of communication.
That's the real problem I think. We all assume everyone online is an ass, and thus undeserving of being treated nicely, and so we all act like assholes to everyone else. We simply don't give the same benefit of the doubt online as we do in person.
