It's a depressing reality that most adults will not progress past stage 4 in Kohlberg's moral reasoning.

The law however arbitrary and flawed is the source of morals for most adults.

George Carlin said it best with “Think of how stupid the average person is, and realize half of them are stupider than that.”

Sadly there are many more simple minded people like this than people who understand nuance and know that legal doesn't always equal right. Even more terrifying, people like this can vote.
