Frankly, if you’re getting a new passport, you should probably just choose the tranny “X,” because it will make you less likely to be abused by the TSA.
If some obese Mexican man tries to feel up your balls, you can say “hey buddy, didn’t you see the X on my passport? This is sexist abuse!” No one wants to get fired for that. He will then send you to the obese black woman, and you can then say “hey woman, don’t touch my balls!”
They will eventually just let you go through the terminal unmolested. No one wants to deal with this.
