My oldest niece (né nephew) is one of those transgender soldiers now (apparently) banned from serving in the military. She retired after nearly three decades of service, transitioning while serving in the California National Guard (c. 2007)
She started her military career -- yes, career -- in the Marine Corps (c. 1976), and after four years, left for a civilian life, only to rejoin the military in the CNG after two years. She stayed in the Guard for over 25 years, retiring as a decorated master sergeant a few years ago.
I don't know many of the details of her service or transition -- at least not in the last few years as we lost contact with her during some other upheavals among the family, and I'm not entirely sure where she is now. Much as I'll bet she's not entirely sure where we are these days.
All I'll add to this right now is that Trump's tweet (whoever wrote it) about banning transgender individuals from the military seemed intended as a disruptive monkey wrench-shiny object, catnip for the media and a vicious blow to a disfavored minority to capture the news cycles while the Senate undertook Repeal and Replace.
It failed mightily.
Anthony Scaramucci put out the idea that Trump was a disruptor operating a start-up the other day. A disruptor yes, but the US Government -- let alone the presidency -- is not a "start-up". Not only will this not end well, I suspect it will end soon.
But then, what do I know? Nuttin'. That's what.
