I can't think of a good phrasing for the question (this is like version 6 or so as I type), so apologies for that. I don't envy your position at all, but I was just curious as I was trying to think through scenarios. I'm lucky that my democratic candidate (the most progressive one in the primary that thankfully won it) considers (correctly in my opinion) that trans rights are human rights. I don't think they'll win (heavily-gerrymandered rural district), but I hope that they do.
Do you worry that, were you to vote republican, it would make other groups in the future less likely to support a candidate in favor of trans rights over one that more directly helps them? Put another way, if your vote causes peoples' rights to backslide, will they help or forgive you for what they might perceive as holding everyone hostage? I would worry that people, especially those whom are not traditionally as marginalized and not having strong opinions on trans rights to begin with, might be less supportive as a whole in that environment.
Again, I don't envy you, and feel free not to answer; I'm just trying to understand thoughts and strategies.
