If you’re in the US, with a two party system, not voting for the less evil is actively enabling the greater evil.
You think Trump or any GOP candidate wouldn’t do the same? Or worse? They’re certainly not going to do anything better than Biden.
Voting on principles is for the Primaries. Try and get the best candidate possible that you actively believe in into the race. Election Day however is when it’s time to put your adult pants on, accept the world is messy, and vote for the least worse option possible, because otherwise you’re just abetting the worst option.
