This sounds like an example of what Lenin was talking about in “Left-Wing” Communism: an Infantile Disorder. Not all the Pro-Palestine folk are well principled, but I don’t think that has much to do with an excess empathy. It’s often hard to tell the difference between treachery and ignorance.
Know when to fight and when to walk away. Battles that can’t be won aren’t worth fighting. Rest if you need it.
