I am baffled how the centrist scold holds both the idea that throwing trans people under the bus is a key strategic move worth doing to win, but also that pointing out they are doing it is what costs Dema elections. If it's what "the people" want, criticism from the left should only help, no?
Heck, if one is so convinced that leftists criticizing Dems is what costs elections, why not try the experiment of running someone who doesn't treat whole groups of people as strategically disposable. Otherwise it just sounds like they don't like reminders of who they're willing to abandon.
