Exactly what would be a better way to defend ourselves against a force which is neither there to protect or serve us? It's worse for black people but it affects ALL of us under tyrannical governments..which is all of us.
I don't know. I know that collecting guns to protect yourself from the police is not a good way to not get shot by the police. Any kind of antiauthoritarian politics in the US is crippled by being spread over too many mutually contradictory ideologies. Get the libertarian left to stop fighting primarily with itself, the libertarian right to let go of enough racism to see that the jackbooted thugs are still jackbooted thugs when they're stomping on brown people, the techies to start noticing that people who aren't their fellows get mistreated by the law too, ... , and get them to come to similar understandings with each other, and you have a coalition that can do things. This does not seem very likely.
I try to make one point from time to time. I feel there's too much focus on distinctions that make a difference. I think the great problem with our current society is not racism, nor is it sexism, or class; consumerism or denialism. Those are all, rather, manifestations of one thing. Assholes. Too many assholes. Or, Authoritarian Personalities, if you prefer. But I think "Asshole" is a better word - it's more difficult to argue that it's a feature instead of a bug.
