I have read this essay a number of times. While I agree it is great, it has an assumption of good faith on the part of the counterparty that I find unsubstantiated in terms of sexists, including many of the anti-Pao folks in this thread. If your discourse consists mostly of repeating unsubstantiated rumors or outright falsehoods, or are otherwise laced with misogyny, like the induhviduals who have made comments about her husband, I feel there's a point at which it is fine for me to give up on you. At that point, the best way to raise the level of discourse is to remove the bad actors from the conversation.
