Once I knew about the Political Trichotomy and internalized it, I can't unseen it.

I was in a Discord server, and there was this libertarian guy debating a socialist about owning yourself.

For the libertarian, it was okay if someone sold himself because it was voluntary and under freedom. But the socialist didn't like it, called it slavery and opposed it.

The libertarian couldn't fathom why. "But it's voluntary." The answer is values. Liberty versus Equality.
