I agree with you that this kind of behavior is annoying. Sort of seems like the perfect storm of short-term thinking, unhealthy huge ego, lack of empathy and emotional volatility. It appears simple enough for anyone to avoid this trap, maybe read the book "all I need to know I learned in kindergarten". Or, most common sense community rules, which usually boil down to "don't be an ass".

Thanks for mocking the foolhardy, and giving us all more food for thought and more reasons to think before we say dumb things.
