And if I also disagree with some of what the other party is doing, then what? "Don't vote" seems to be the only option you have left. And I strongly disagree that that's the best option.
Then you compromise and pick the party that you think best accomplishes what you want.
But part of that compromise is that you accept the party is going to also do things you don't like. Which is something you can't escape criticism for. Voting is approval for that party. You're choosing to value what Party B does over Party A, which means you weigh the negatives of Party B as being less of a problem than the positives.
That doesn't mean you get to avoid those negatives when someone else calls you out on who you decided to throw your lot in with.
