"Let’s begin with the retrograde cruelty. There are thousands of transgender people already serving among the 1.3 million active-duty members of the military. These are people who have volunteered their service and have potentially put their lives on the line, and yet their President, who managed to come up with a flimsy doctor’s note back in the day, denies them their dignity, their equality. He will not “accept or allow” them in the military. Imagine the scale of this insult...
It is implausible that Trump paid much attention to his highest-ranking generals, or to experts, generally; Secretary of Defense James Mattis has supported transgender individuals joining the military. And the hardly radical Rand Corporation has published an in-depth study refuting the idea that transgender soldiers are somehow expensive, or that they undermine the morale and cohesion of the military over all. Trump’s decision to bar transgender people from the military is pure politics, cheap and cruel politics, a naked attempt to divert attention from his woes, to hold on to support from his base—a base that he believes will cheer his latest attempt to do battle with the secular-humanist coastal élites who are so obsessed with identity politics. (One Administration official told Axios’s Jonathan Swan that the move was intended to force Democrats from Rust Belt states to take “complete ownership of this issue.”) In other words, it is a decision straight out of the Steve Bannon playbook. Cue the organs of the alt-right press.
Trump likes to declare what a “disaster” the military is, how deeply it has fallen into disrepair, and how he will be its salvation. When you begin to consider the meanness of what Trump has done, it is worth remembering him saying that he was “smarter” than the generals on military matters, and that he mocked John McCain’s service in Vietnam because “I like people who weren’t captured.” When you begin to think about the scale of this offense, it is worth remembering Khizr Khan, the Gold Star father who lost a son in Iraq, addressing Trump directly from the lectern of the Democratic National Convention: “You have sacrificed nothing and no one.”"
