I’m not in a position to evaluate which of these causes outweighs the other, and I’m sure I’m grossly oversimplifying a complex situation.
One can object to Israel’s violence against Palestinians without first having established equal and comparable bona fides by condemning, say, the Saudi monarchy’s obscene and utterly pointless violence in Yemen. There are no teams but those with power and those without, my side always being on the side of those without power, and we don’t need to “both sides” every bad thing by identifying bad acts by a competing national team or racialized Other to condemn in balance.
