Anti-authoritarianism is a cross-party position. It just depends on who is in power at the time. There are also contradictory positions on both sides.

On one hand, some liberals will take on the "defund the police" and "ACAB" position, but others will also say that only police officers and the military should have firearms and ordinary citizens in practice don't have the right to defend themselves.

On the other hand, many conservatives will lean into respecting established authority structures and institutions. Police are respected because they maintain law and order. However, American conservatism also has a deep foundation of individual independence and pushing back against government overreach. It is better to rely on yourself first than wait for the police to come rescue you, especially if it might take 20 minutes for them to get there.
