Those indoctrinated by leftist thinking become largely incapable of making accurate moral judgments.

Much of the world's moral compass is broken. The moral north reads south and the moral south reads north.

As you get older and wiser you realize that when people are given anything without having to earn it (unless they are physically or mentally utterly incapable of earning anything), they become ungrateful and lazy. They also become less happy.

Therefore the vast majority of the people who affirm leftist beliefs think of their views as the only way to properly think about life.

Goodness is about character - integrity, honesty, kindness, generosity, moral courage, and the like. More than anything else, it is about how we treat other people.

The Left has taken over the universities and, increasingly, high schools and elementary schools. It dominates the news and entertainment media. And many judges and courts are leftist - meaning that their decisions are guided by leftism more than by the law or the Constitution.
