You're not talking to serious people, their anticop mentality stems from.sensoble thoughts like "corrupt cops are bad' and 'the system is often unfair' but spirals into a dogmatic hero fantasy where they get to kill people they dislike and win every gunfight just like the movies of the old west.

Of course those stories of noble outlaws doing right by the people are fantasy and the reality is a mass of cruelty, rape, theft, murder and violence. They have this idea that they'll be the tough guy with a gun who can live life however they please because they don't have compassion for other humans, not the old, sick, weak, and certainly not women, children, or those the work hard to live a good life.

They think that you're weak for wanting an official body who's job it is to enforce the rules of society because they love to imagine themselves as an untouchable hero that doesn't need rules, also they love the idea of people needing them for safety - a woman being able to live somewhat safely through a system of laws and justice upsets them because they'd love to be the strong man with a gun that women have to keep happy and near if they want protection.

Every anarchist autonomous no cops zone instantly gets a gang that act like cops without any of the hard fought and long studied protections for the people - and bigger areas where law governments collapse get lots of these gangs who all fight each other... thousands of years of shitty history lead to the development of established and regulated police forces - yes they're far from perfect but we need to work on improving them, adding oversight and better training, new systems and organizational structures.
