Err...sir if you read back, you will realise she/he was spreading misinformation and yes everyone makes mistakes but when someone corrects you, you shouldn't behave like an arrogant prick. You are contradicting yourself. You've been wrong many times yourself. If Bear or some other veteran came and corrected you in a straight but polite way, would you behave like an ass? Don't be a hypocrite please.
And if you truly believe your own words, you would have stopped that person then itself. I tried being nice and polite but if a person is going to be an ass to me, I have no obligation to continue being nice.
In simple words, you do yours. I do mine. Peace
