There is some irony there, because a common tactic for derailing complaints of sexism towards women is "maybe you're right but you said it in a way that hurts people's feelings, so we're going to ignore you. Try again next time."

I think the challenge is there is disagreement about who is the aggrieved party. Are women aggrieved because the memo made them feel unwelcome, or is Damore the aggrieved party because he was raising a grievance?
