Referring to the only female Professor in his (mathematics) department, a Professor I know told me "she only got the job due to affirmative action."
He seemed to be saying that she wasn't good enough to get the job on her own merits. The conversation could have ended there, but I persisted.
"She's an excellent mathematician. I think she's better than almost all the Professors in your department," I said. He agreed with that.
"Then why did she only got the job through affirmative action?" I prodded.
"Well, one of my colleagues was prejudiced against women, so he fought against hiring her. Affirmative action was needed to overcome the prejudice of that colleague."
Whatever one's views on affirmative action, it seems to me that this was a case where it made the right thing happen.
