Me, I didn't think that wingo's comment was "politically correct". It was very welcome and if there hadn't been such a comment already, I would have wrote one.
Maybe, in your part of the world, "critic of sexism" is "politically correct" and thus to be avoided -- in my part, it ain't so. (I'm not from the USA, to make that clear.) We criticize sexistic remarks because we want women to feel welcome in our circles, not because it is "politically correct" (whatever that means today and for you, I don't care).
And if you think such comments would not deter women, you might want to come out of your closet into the big blue room.
