If you're in the UK, pinch your nose and vote tactically today. Most of the time that will mean voting Labour, but check the polls (such as YouGov's MRP) for the best-performing left-or-centrist party.
I can entirely understand reluctance, especially if you're a member of a marginalised group: rhetoric in the UK is, in technical terms, 'fucking dreadful' right now.
But the reason it's become so dreadful is because the right has used bigotry as a tool for building power. Get rid of them.
Another thing I'd like to remind you of: there is nothing morally compromising about voting for a party that you don't see eye-to-eye with. Voting is harm reduction. It does not require you to stop advocating for whatever ideas you want to advocate for.
I can absolutely promise you that whatever state of the world you favour (albeit fascism, but fuck off if that's your preferred state of things) does not lie on the other side of letting the worst of two evils run rampant.
