Military isn't boy or girl scouts. Show me a transgender person that you want flying your commercial flight. The pool of emotionally fit qualified people will be very small.
It isn't necessarily based on bigotry and hate. I know what my eyes see and my interactions tell me. A person that I know went through the change. I can talk to them all day about Ag. I would never want them flying my plane.
What we did to blacks at Camp Dodge was bigotry. I don't know anyone trans that isn't an emotional mess. A lot of that (don't know how much) is bio/chemistry related.
The military isn't a social experiment. I doubt you know much about the military. If you did you would know better.
Listen to this interaction between a male FTC and a female pilot.
Tell me you can't hear issues in the conversation.
The woman took a "damsel in distress role". FTC took an "I'm going to help a damsel in distress role".
Neither of them took on an androgynous role in the conversation which is really what you are getting at.
The military isn't boys and girls carrying toy guns. The job of the military is to kill the enemy. There are natural differences between the sexes which for some reason you ignore. Transitioning doesn't start one and stop the other. Hormonal imbalances in anyone can create chaos. This is ripe for chaos.
The military isn't a job for chaos. It's being precise in a world of chaos.
