I think there’s a pretty key difference between expressing sympathy and support for Palestinians, which I’ve seen plenty of from all kinds of people - including most recently literally Obama - and looking at the murder of over a thousand civilians and saying “this is fine and justified”.

I’ve seen little to no criticism of people who have merely expressed simple support and sympathy, and much more criticism of people doing apologia for the intentional murder of children. If that were to change, I would be greatly concerned, but that’s not really what I’ve been seeing.
