Was wondering how you feel about Rachel Dolezal? If gender and race are both social constructs, does she have the right to choose her Race? The only argument I have seen that differentiates her from Trans people is the claim that being Trans is not something you can try on like a costume, because Trans people suffer so much when they don't transition. That seems to be Transmedicalism, from your description of it.
Also, If sex is different from gender should we continue to differentiate sports competitions by sex? There is a dilemma involved in that issue which I discuss here.

Please understand that these are not rhetorical questions attempting to trip you up. I don't know the answers and would appreciate hearing your thoughts.
