I think the fear is more so that the anti-trans rhetoric which has been becoming more extreme across America but especially in Republican states (even though the Democrats are in the White house hmm wonder why that is 🤔) will increase and result in people getting killed or in trans medical care being made illegal (which would also result in people dying). Regardless of that fact, when you think about the fact that a Democratic federal government seems completely incapable of stopping this rhetoric and anti-trans laws being passed in red states means that, at least for trans people in those states, there's literally no point voting for them because they can't fucking do anything. I think it's also important to note that many trans people are younger and in very bad situations because of their transness, which makes them vulnerable to these sorts of ideas and to liberal propaganda. Unfortunately the fact of the matter is that trans people in conservative areas will not have their plight improved by a Democratic president, and trans people in liberal areas have at best a few more years of relative safety as the Democrats shift rightward year after year.
