I never hear anyone engage with the point of "If Israel is genociding Palestinians, when are they going to expel the ~250,000 Palestinians in Israel?' The fact that they're not doing that is a counterfactual the conflict is not ethnic-based and therefore could not be a "genocide" definitionally.
Most self identified Arab Israelis are Arabs who were in the area during the mandate and stayed, or their descendants. Of course, they'd say "Israel is an apartheid..."
But then won't give a single other example of apartheid where the supposed targets can own property and businesses, actively serve in the military and as politicians, etc. They need to believe that "those Jews" did the very thing Hitler claimed "those Jews" were doing all along.
