I believe this comment is turning an issue of sexism into an issue of impoliteness that's developed around the culture of gaming, and I think that's a particularly toxic viewpoint.

Rather than addressing the real fact that women are treated as sexual objects by men generally, whether in thought or anonymous action in message chat boxes, this sort of comment turns it into an issue of "polite conversation". To me it seems as an (although it seems inadvertent) attempt to divert the attention from the real issue towards a non issue of "poor taste in jokes".

I still like particularly dark, demented, and a "punching down humor".

I've always felt a certain level of dishonesty amongst individuals who use polite discourse as a means of communication. There also seems to be a hint of classism in maintaining polite discourse.
