I disagree. How am I supposed to trust and feel safe around someone who knowingly voted for a politician who loudly campaigned on removing my rights and demonizing my very existence?
A politician who supports an esoteric policy that disadvantages me in some way is entirely different than one who loudly and plainly says that I am less human and should have fewer rights than others. That rhetoric kills people. And it's not a deal-breaker for you? I cannot call such a person a friend. A vote for a Republican in modern times is an expression to trans people that their rights and safety are less important to you than whatever esoteric tax policy or whatever than won your vote.
You can value that policy more than the rights of trans people if you want, that's your prerogative. But it will make trans people and their allies trust you a lot less when they discover that you think their rights are just a bargaining chip to be traded away, and justifiably so. What other situations are you willing to throw them under the bus over, not just in politics, but in life? It's not just a matter of pride or preference, but a matter of rights and safety.
