Look, what you're trying to to get at here is that by voting for one party, you're affirming support for their policies. Perhaps the best way to frame this is that this is a little like the trolley problem, in that I can choose to do nothing and let the trolley (the US political system, in this case) run over five people people (Trump stops any finger-wagging at Nettanyahu and probably encourages a similar attack on the West Bank, as well as starts rounding up and deporting anyone with any detectable melanin levels, as well as going all in on climate change on the side of CO2, as well as whatever the fuck else who knows), or I can become a participant and pull the lever to try to make the Trolley run over one person instead (Biden's half ass finger wagging at Nettanyahu). Is pulling the lever problematic? Yes. But I think not pulling the lever is objectively worse.
