You are asking the wrong question. But, maybe not support Hamas in the first place?
For years, Netanyahu propped up Hamas. Now it’s blown up in our faces
Israeli support for Hamas
The right question is this: How is it that vast swaths of the population lack the simple, basic human morality to reject genocide?
We're both squids. I don't know if you were ever out in the fleet, but if you were, then surely you have done what so many other sailors have done over the past few millennia. And that is, go out on deck on a clear, dark night and marvel at the stars. Nothing like laying back on the flight deck and getting a sense of your place in the universe. And I absolutely do not mean some sense of "smallness" when I say that. Quite the opposite. Each individual is unique--there will never be another one of you--but at the same time we have this in common: As a human being, we can co-participate in ongoing creation. In fact, it's our duty.
A small part of the responsibility each of us has is to do the right thing. Sometimes the choices are not so clear. Sometimes the choice is crystal clear. In this case, deep down in their soul, every single human being knows that genocide is wrong.
So, Clapton, think about those stars and do your duty.
