why not just let lose of this crippling desire to align ourselves with some historical identity
Fair enough. Counterpoint: It doesn’t freaking matter what word we use. No matter what the word is, the right will attempt to poison it and stir hatred of it and assign meanings to it that aren’t real. Look at what happened to “woke”. It will keep happening, because the modern right is Fascism, and poisoning language is a fascist tactic that goes back to the very beginning. You call yourself an Anarchist; where on Earth do you live that nobody has negative associations with “Anarchist”.
Use whatever word you want, just use it consistently. Don’t expect it to stay free of propaganda, because they do that to our words on purpose.
You’re asking this in a community that’s specifically about doing piracy. Pretty hard to take your question seriously in this context.
