Again, I agree with what you're saying in principle, but how do you propose to draw that line now?
Both realistic outcomes of the election involve the US government continuing to support this genocide in one way or another - that's why OP's meme is drawn out like it is, because people arguing your exact viewpoint seem to think there's some magical third track everybody else has missed that sidetracks this issue entirely.
Everybody loses this election no matter what happens, but I guarantee you the loss will be worse with the Republicans in the driving seat.
