What pressure are you putting on the guy? Guaranteeing him your vote is the opposite of pressure. It reads as endorsement or at least tacit approval of his policies. Assuming Biden actually cares to win the election, the best thing to do is threaten to withhold your vote. He still has five months to change voters minds. Let him see the polling, let his campaign see the mood on social media. Genocide is a red line, and it’s a low fucking bar.
