I think there is a legitimate question buried in the sarcasm that is worthy of an answer. I know intersex people, so I know sex and gender are far more complex than the simple dichotomies conservatives would force on the conversation. However there is real confusion around gender identification that contradicts one's biological sex.

Why is a white man self identifying as a black man self evidently absurd, but a penis person self identifying as a woman is reasonable? While I don't care how anyone identifies around gender, I do have a problem with some of the politics of the trans movement. I frankly find it reactionary to challenge gender dichotomies by transgressing them, but in a way that reinforces the essentialism of the dichotomy. The non-binary movement has it right: end the gender binary once and for all. Penises and vaginas, and everything in between, shouldn't matter.

Unfortunately, however, they do matter, and the dream of ending gender, and thus making sex irrelevant, will only be attained when we end sex discrimination, specifically sexism against women.

The trans movement distracts from this more fundamental (in my view) struggle, elevating the plight of a tiny minority of gender nonconformists above the historical struggles of women for equal rights.
