No you actually can't be anti-"the only group resisting genocide" while also being anti-genocide. This is like being against apartheid in south africa and telling the ANC to disarm.
You can't believe in an ethnostate settled on other peoples land and be against the government doing settlerism.
These positions are contradictory. Either you want the jewish supremacist ethnostate to settle palestine, you don't or you have no opinion. But you can't have an "israel" without jewish supremacism, that's why it's called "israel". It comes from judaism, it's about a land just for jews. You either support the palestinians right to return, or you support "israel". Because you can't have one without the other. This is not a policy thing. This is baked into the very foundation of this so-called country.
