“Its 2026 and in my third week here on North Sentinel Island, I’ve discovered that, despite a century of a world super power using the word ‘socialist’ in the name of their country, somehow these people have never heard the word, ‘socialism’”.

Well, some people just never learnt English

trying to get you to stop caring about what someone.calls themselves and start caring about what they do.

Guess what? I always ever really cared about what people do. And someone calling themselves something is part of what they do, for whatever reasons they do.
I don't have a problem with this part. My problem is the direction you take after this conclusion. Words will always mean something to people and when someone calls themselves a part of some groups or when someone calls others a part of their group, politics takes over from that point. That affects the masses and masses have power.
So even if I actively try to stay out of said "masses", doesn't mean it won't affect me.
