Israel is currently genociding Palestinians under a Democratic president, they didn't need Trump's approval for anything. The bulldozers are already running, the people are already having their lives destroyed.
Again, I voted Harris for harm reduction, so I see your point about Harris possibly being better for Gaza in the long run, but it's not "kill my friends now" or "kill my friends later" it's "kill my friends now" or "kill my friends now and maybe, just maybe, stop sometime around the midterms when it's politically convenient and only if Harris doesn't need to keep getting the fascist vote". I don't blame Gaza voters for looking at that choice and holding out for what they really want, which is "stop killing my friends now".
Everything on that list is typical neoliberal Democrat tinkering around the edges while the world burns.
It's not that the individual ideas are bad, it's that they have no vision of a better future for most people. Where is Medicare For All? Where is tuition free college? Where is anything that isn't just a bandaid for a specific paper cut when the whole goddam country is being devoured by fascists and corporations?
That's the meat I'm talking about - something that millions of people on the left could vote for in self interest. What we got was meat for checks notes non-Medicare diabetics.
