Were the “anti police” people at any of the protests for Ashli Babbitt? Were any of them any of the protest for the prisoners being held for crimes like “conspiracy to commit interstate commerce” after the January 6th riot? How many anti civil asset forfeiture people also believe in “red flag laws”?
Leftist political philosophy is authoritarian; that doesn’t mean that sometimes left-voters don’t accidentally protest authority when it suits them.
A violent revolutionary trying to topple a western liberal democracy to replace it with a communist dictatorship is locally anti authority, but authority is still the core of the political philosophy. They just want to get rid of the existing authority because they don’t think it is strong enough.
