As a white Christian myself (yes, you can be trans and Christian), I don’t see us being alienated in that regard, unless you are a single issue voter on something like abortion. In which case, yeah, those people don’t really have a choice in their votes given polarization in said issue
What I see often in Christians is a mindset that Christians are being persecuted in the United States, which isn’t really the case.
While I do feel concern sometimes about sharing Christian beliefs in a non-Christian area, it’s only really because I worry a take will be unpopular. However, replace the word “Christian” in this paragraph with “trans”, then it can very well be life or death in many cases. In the former, it’s really only be my ideas being challenged (which I am no stranger to, especially here), but for the latter, coming out could put me in physical danger.
What I’m trying to say is, no one (or at least any significant amount of people) in the U.S. wants Christians dead. But many do want trans people dead. You’ll see a significant number Christians voting for Democrats, but, and correct me if I’m wrong, you’d be hard pressed to see trans people voting for Republicans, at least with their current platform
