Biden has agency here. He could very easily get my vote, but chooses not to. He's making conscious decisions with expectations to how people will receive them. That leaves us with two possibilities, which I alluded to earlier:
He cares more about genocide than winning the election.
He thinks he can win without the anti-genocide vote.
If it's 1, I don't want him as my president. If it's 2, he's not expecting my vote and nor shall he get it.
