Ah, yes. The GOP is eliminating trans health care, trying to force them out of the public sphere entirely, and calling for trans people to be institutionalized or worse, and matty's prescription is for Democrats to stop "elevating the salience of trans issues."
I think you misspelled "telling Democrats to throw trans people under the bus." He's built his entire brand on telling the left that they're panicking and are sinning by actually advocating for the things they believe in, even as the GOP has become a full-on fascist party.
He thinks the way for democrats to advance their agenda is, somehow, to run as center-right politicians, and then suddenly do a bunch of liberal stuff when they're elected, without building any popular support for it, much less defending it against right-wing attacks.
As the GOP has ascended by relentlessly pushing its message and building a base on that, he tells Democrats the last thing they should do is take a principled stand and advocating for it. I'm sorry, but he's been of far more use to the GOP than the beliefs he claims to hold.
