the only people left defending isreal are literal genocide apologists

I think there are lots of persuadable people out there who very deeply want to believe the U.S. does not do these sorts of horrible things (or at least doesn't do them anymore). They don't see a genocide and think to apologize for it, or deny the reality of what they see -- they start from the premise that of course we aren't doing genocide, and reject anything that challenges that too directly as biased or misleading. It's a set of mental reflexes designed to avoid uncomfortable contradictions like "if the U.S. is right now doing a fast-motion genocide under a president I voted for, how do I respond?"

There's another large group of people who aren't really genocide apologists: people who don't follow politics of any kind very closely, and who have a similar reflexive rejection of anything they see as too radical of a political stance. These are the folks who nod along to all of our critiques of capitalism and the U.S., but punch out when you label those critiques socialism or communism.
