Upon reflection, I don't agree that gender norms are entirely social constructs. I think the basic themes are inborn, while their expression can be malleable within a particular society.

I don't think it's useful to attack the norm concept. It's useful and, I think, it's necessary, because it reflects reality. Men and women are different, and therefore will express themselves differently. That isn't going to change.

Rather than attack the norm concept, I think we should instead admit that we don't fit into it, for whatever reason, and that's ok.
