Leftism is rooted in ingratitude.
The left has ruined the arts; the universities; high schools; the nuclear family; mainstream religion; the Boy Scouts; and journalism. And it is now doing the same to the sciences: Universities are increasingly choosing science faculty based on gender and race rather than on scientific expertise.
One of the most important issues in human life is determining what is right and what is wrong. The right brain (feelings) has triumphed over the left (reason and values). At least two generations of Americans have been raised not with moral instruction but with the question “How do you feel about it?”
The Left asks “Does it feel good.” The Right asks “Does it do good.”
