Why the snark? It would be trivial to add another gender option to the page, and it would make the world a slightly friendlier place to a few people. Must everything be an argument?

I agree. I self-identify as black and refuse to fill out forms that force me to select my ethnicity.

Since when do you register your gender with the TSA?

Whenever I fly, I just walk through the checkpoint and move on to my flight.

When you purchase your ticket, they ask for your name, date of birth and gender.
