Two wrongs don’t make a right. Criticizing Israeli actions is not implicit approval of Hamas actions.
The challenge here is that Hamas are generally considered to be the bad guys. You expect the bad guys to do evil shit.
Israel is supposed to be the good guys in this scenario. Being the good guys means you are not expected to do evil shit, and are supposed to do the right thing even if it is harder. Except right now they are doing orders more magnitude evil shit than the bad guys. I don’t think it is unfair to call them out on that.
