Not American, but I am in a similar situation every time I vote. I don't want right wingers to win, but our leftist parties are batshit crazy (not specifically for trans issues yet, but for other things).

I can't bring myself to vote for the left anymore, they are showing that they are completely unable to think and a level of hipocrisy, arrogance and general hatred towards the category they claim to defend (and in fact are exploiting) that I can't ignore.

I don't think making them win is a good strategy if you want them to change their tune. That said, I don't think they are even able to change their tune because they are so far up their own asses that they wouldn't admit they are wrong even if truth clubbed them on the head. So basically, I simply do not want to be responsible of putting them in power and of what they will do during their mandate.

If I were American, I wouldn't vote for Trump, but I wouldn't vote for Biden either: I wouldn't want to feel responsible if a TIM gets access to a rape shelter or prison and assaults one of the women there and then witness official organizations telling those women that they must respect their rapists by calling them ladies, I wouldn't want to feel responsible of girls losing their scholarships and privacy and be attacked for transphobia, and if things are going the way I think, I also wouldn't want to feel responsible for all the children who will be transed in the next 4/8 years.
