I don't disapprove of the EO if it happens, however, I think there are a few cases that should be vetted before they are released. There are some gay women who might like to think they are males, who might be very butch or dyke in their appearance, but who are also patriots and darn good and loyal service members. I happen to know a couple of them personally as they are long time friends of my sister who is a lesbian. I've known them for going on 40 years now. They actually happen to be twin sisters. One got out after her time was up the other stayed in for a number of years beyond that and retired from the military. My wife actually worked alongside another person like this for a little while recently and got to know her. this gal considers herself a dude and served honorably, voted for Trump, and was actually in Homeland Security doing special operations rescuing children from traffickers. She/he gave that up after the second time she got shot. She/he's working a civilian job now. Regardless, they all served our Country well.
Now if there are Tranny's just joining so they can use the service to get a free transition, or if they are obviously mentally unstable with gender dysphoria, and are going to be narcissistic and a problem, then they need to be gone. I'm just pointing out that there are some who don't make gender identity, their primary focus. They're just some butch's who want to serve like any other service member with no special treatments.
