I chose to vote for Harris despite this because Trump would be no better on this, so effectively the issue wasn’t up for vote and I could only vote on the other issues that were different between them. But very bluntly, I don’t blame Arabs and Muslims for not voting for Harris. They have one of the strongest grievances one could possibly have (i.e. second only to attacks directly on them personally, in the U.S.), and the dismissiveness from Biden (and Harris) was downright insulting.
A part of me does feel like Biden chose Israel over Americans. I don’t know if changing course on this would have changed the election, and I guess it’s impossible to truly know.
