Honest question, does he really have to be male if he doesn't want to, and if so, should he be held to those standards? Take the example of the TG boy in Colorado who decided he is a girl and was recently granted legal permission to use the female restroom even though he retains the male plumbing. Other similar cases have occurred and are certain to move into the military soon. For example, if a man declares himself a woman and is recognized as a TG female, does he then PT test under the female standards? Does he begin wearing the female uniform items?
I think that between these issues and the pending allowance of females in all combat units, we're very close to the only right answer being gender neutrality in every aspect of military service. That would mean everyone is held to the same PT standards. It would mean uniform requirements become gender neutral, with either everybody (or nobody) being allowed to wear heels, skirts, earrings, nail polish, long/short hair, etc... I'm honestly not sure our gender discriminatory standards will stand the legal test of the next few years. I can't say I agree with it going that way, but with the issue of gender becoming so muddy I can't see how it wouldn't.
