I get your sentiment, but The military is one place that can’t afford to get the wrong people in the wrong positions. Menials can still get access to classified data, like Bradley Manning did.
While I agree with you, military service had long been diversion for those with spotty records. So has entry level jobs. We want them to work, except we don’t want them to work.
I think we’re safer with taking folks with ADHD than with sexual dysphoria.
