This for sure is not the place for the hyper-sensitive. It is best to let the real or perceived insults roll off one's back, and carry on regardless. My motto is; "Never enter into a battle of wits with an unarmed opponent". Needless to say that has saved me a lot of aggravation.
I will say, however, that it is not easy to keep a sense of perspective when some goof tells you it would be better if you left the board, as it happened to Eric some time back.
