Earlier quoted context omitted.
I'm not sure why something becomes "unacceptable to society" just because it "poses a threat to feminist aims." What's the first principles reason why it should be unacceptable?
It's not really something that can be well summarized in a hn comment, but basically, it re-enforces the idea that men and women are actually so different that you have to be a certain gender just to do something you want to do (gender essentialism). My main point is, if it were acceptable, my s.o. would have a blog post about it that I could just link you to.
Now I need to really think about this...
