You and I may not be able to read minds, but it doesn’t matter. You can usually tell what someone is thinking by what they are doing— their inner thoughts and beliefs become outward acts.
Even in those cases where their behavior conflicts with what they think, you’re better off responding to how they act rather than wondering what they might be thinking. How someone acts is more important than what’s in their mind.
It comes down to this simple truth:
I don’t care what someone believes as long as they act like an anarchist.
Which most people do, most of the time. As long as they don’t try to control, rule, rob, attack, etc. others– including me– that’s what really matters.
And really, isn’t that what everyone– even every statist– wants from others?
I don’t see people behaving as though they like being bullied and robbed, even when that’s what they advocate, politically. That’s because politics is self-contradictory and internally inconsistent. It fails everywhere it is tried, and always has.
