This person does not speak for the entire uncommitted movement. Many people participating will not be voting for Biden come November. And more importantly they won't be participating in any GotV campaigns for the general. There won't be any "heroic" GotV campaigns that carried Biden in 2020. I won't call it for Trump yet. He might not have any juice left in him either. But its going to be close.
If Biden wants my vote he can show he has the strength to twist Bibi's arm. The longer he takes the harder he better twist. His October surprise better be a No Fly Zone over Palestine, '67 borders. Obviously, he won't. But if we can pretend he will I can pretend I'll vote for him. Asking thousands of activists to not just vote for genocide but actively campaign for it is more futile than harassing Biden.
They can mald all they want. I'm voting Jill Stein because it'll be hilarious if she were to get a substantial portion of the vote in a swing state. You couldn't pay me to vote for Genocide Joe so I'm just going to use my vote to piss off people.
