In one of my first posts I referred to you all as "happy, shiny poker people." I'd like to put some emphasis on that. Don't be "grumpy, narcissistic poker curmudgeons." Firstly, people won't want to play with you; secondly, the phrase doesn't roll of the tongue.
I've played against my share of rude and obscene opponents, and there is no call for it. In the digital arena, they hide behind their avatar, saying things they would never utter in person. After all, no one gets their butts kicked in an on-line flame war, but I think this is a symptom of a larger problem.
Poker isn't perceived as a fair game, even when there is no cheating. The poker gods giveth and taketh away on the river far too often. If you can't come to terms with that, you shouldn't play.
