once again, you're making this into a voting issue when it isn't one because neither party is interested in taking your preferred stance. naturally, withholding a vote because of this makes no sense especially when the stakes on other important issues are so high.
I understand how strongly you feel about this issue. I agree with your feelings about it. I would love to see the Israeli govt get pulverised for what they are doing. and it is objectively atrocious in every way that they are supported.
I can also use my brain to logically determine that refusing to vote dem is likely to put power into the hands of those who will do worse both on this specific issue and many others. voting for Biden might not make it better, but doing anything else will definitely make it worse. and that's the brain dead choice.
