I've had the nerve to neg-rep a sage here. Sages can be ass-hats, too. This particular post belittled a person and I don't give a flying, er, doughnut who you are or what you've sold, that's just plain nasty and I won't let it go unchallenged.
Mostly I feel free to speak my mind publicly rather than neg rep. A great many people actually apologize, publicly or by PM, for getting so heated up they spoke rashly. I tell them it's okay, we all get mad, but that learning to think before you speak is a skill worth having.
God, I'm such a mom!
