The state is NOT a mediator of white supremacy or settler colonialism. We cannot expect it to intervene or interrupt settler colonialism, it is a facilitator of land pillaging and white racism and settlerism and was formed out of that very same violence.
The state is not moderate, neutral, or an instrument of regulation, it is a means of enforcing colonialism, capitalism and hierarchy. It achieves this goal through constant aggressive intervention against non-whites, by institutionalized oppression via courts, policing, prisons, poverty, and selective non-intervention/endorsement of (seemingly vigilante) acts of white terror that are actually much broader and rooted in historical violence and the maintenance of the state.
This is why we have to prepare for both the white militias and the state, because either the state won’t be intervening against white reactionary violence or it will be actively intervening with repressive violence against those defending themselves.
