Assuming we are talking about meatspace here...

I just tell people I am an anarchist.

They then nearly always project some insane nonsense onto what they think that means, and then I understand at least 80% of their worldview in about 30 seconds.

I am done explaining things to angry morons with no curiosity or humility.

I actually do not care what they think, I have better things to do with my time.

If they present humility or genuine curiosity, well then, that's probably a person worth at least a bit of my time.

Alternatively, I tell people I am an ex-corpo cyberpunk, because I literally am.

If they don't understand that, or laugh at it, I act confused, or laugh at them.
