Nobody will ever wake up without self examination.

Instead of telling people to believe what we believe, we can ask them questions to get them thinking about their own beliefs, for example ask a liberal something like

"If everyone made the same amount of money regardless of their job and we had true income equality, would that change equality of outcome?"

It wouldn't. For example some people would just drink all their money away regardless. Not to mention the obvious loss of freedom to pursue your own individual prosperity and happiness.

We can't spread light by force, at least in my experience.
