When he responds with "You hurt my feelings when you did X" he is piling on and contributing to her abuse? Her attitude would've hurt my feelings. There seem to be no acceptable avenues through which to attempt any sort of conflict resolution with Shanley. White men are just expected to be silent and let her disparage any work they do that doesn't meet her world view.
Thank you Chad, for making the world a better place with your work. I disagreed with how you implicitly supported a sexist comment on HackerNews but I think that is a forgivable offense and that the good you do with Gittip far outweighs the negative of that action.
