I think you might want to consider that this issue is being megaphoned by people with ulterior motives. Not a single trans person I know cares about this game, and this whole vitriolic thread is about a tweet with barely more than a hundred likes. Have you seen Hogwarts sales? I'd be willing to bet the game is doing fine. Nothing got cancelled. This post is obvious ragebait, and loads of people here are falling for it.

As for the substance of your complaint, I'm with you that people shouldn't be using threats of violence. There are shitty people in every group, and that includes marginalized groups like the trans community. Plus there are people in every group with experiences that blind them to context, who aren't necessarily terrible people but who might have trouble avoiding the influences of self-serving biases (Rawlins being an apropos example). That sucks, but it's not necessarily representative, and those people are reprehensible. And it's clearly not "virtue signaling" to help one group of people that need help without expanding the effort to all people that need help. A surgeon that only does brain surgery isn't a bad person for not also working on the cancer ward. He might be a bad person, if for example he holds cancer patients in contempt, but that isn't a logical deduction from just the fact that he only does brain surgery and it isn't logical to assume that people fighting for trans rights don't care about other people's" suffering just because they aren't marching in those rallies. Henry David Thoreau touches on the moral imperative to fight injustice - Walden is worth a read.
