>>> “That makes me wonder — if a female has a sex change operation after her 18th birthday, would she/he have to register for selective service?”
Incredibly, one of the links posted upthread answered this. I even think it was the official sss.gov one.
In short: a male who was born a female is not required to register. Not specifically addressed is whether a female born a male is still required to register. Of course it’s a moot point in terms of actually serving, but you can count on it that some extremely disturbed individual with an axe to grind is working on it right now, LOL.
Wouldn’t it just be easier to hit on your platoon, and then “admit” that you were gay?
