Just give'em a straight left.
Behaviour

Is it just my imagination or have anyone else noticed how badly other chessplayers treat other players here on chess.com? I think that almost every comment I see on someones wall is mocking that person and very often when playing live chess opponents need to mock other players if they are themself loosing.
I have played over 300 live games and only once has anyone mocked me and that was just when he said "LOL" after he owned me. ::shrug::

I'm always fascinated by members who draw broad and sweeping conclusions about +6,000,000 other members based on their decades of experience here

I havn't played a lot of games here but I've never suffered deliberate abuse from anyone. About the worst behavior I've experienced is when I wished an opponent 'good luck' in the chat & got no response!
It's only a very small percentage of members who behave badly on this site & you can often deal with them by challenging their bad behavior but always be polite about it - never sink to their level.
As a last resort, just disable chat during games & block abusive people.
