After some months thinking about the nature behind the "vote blue no matter who" and the "every non-vote is a vote for trump" and the "single-issue voters are dumb", I've come to realize that libs simply are doublethinking about the power of votes in the US.
The lib doublethink on voting power is as follows: The votes of some leftist minority are powerful enough to tilt the elections one way or the other. Simultaneously, the votes of those leftists, and of the rest of anti-genocide libs, aren't powerful enough make the Dems shift to bringing a stop to the genocide.
If the US is supposedly somewhat of a democracy, they can both tilt the elections and influence democratic party policy by doing so.
If the vote is useless and they can't change the policy of democrats by conditioning their vote to a stop to genocide, then they don't live in a democracy and voting to either party simply amounts to enabling genocide in an anyway undemocratic system
