It's because those positions don't actually exist on the "radical left" (which is a term coined by conservatives to discredit moderate left political policy). "Disbanding the police" is a strawman thrown up by the American mid to far right in response to centrist to center left proposed police reforms and supporting the Israeli genocide is antithetical to leftist values. It may be in line with the American Democratic party, but they're quantifiably a conservative party.
You're criticizing non-existent leftist policy and non-leftist values using pejoratives coined by the right while claiming to be progressive. It's just odd.
