As for the secular world, irrational beliefs permeate the left. For example, a generation of Americans has been educated to believe that men and women are, beyond physical differences, the same. Boys don't inherently prefer trucks and toy guns and girls don't naturally gravitate to dolls and tea sets, we have long been told. Give boys dolls and tea sets and give girls trucks and they will love to play with those things. Is that rational?
Or how about the tens of millions of people who believed Marxist claptrap about the inevitability of socialism? It was "scientific fact," the world's left believed, that every society goes through three stages: feudalism, capitalism, socialism.
And given the inability of any welfare state to sustain itself economically, is it rational to advocate the continuing expansion of government, as supposedly rational New York Times columnists do?
Is the belief that 50,000 Americans die each year from secondhand smoke rational? Is the certitude that we know what the climate will be in a half century rational? Or declaring sixth-graders guilty of sexual harassment for engaging in innocent, normal-boy behavior?
It seems to me that our secular age is a more irrational one than when America was more religious.
Rarely has the warning to get rid of the beam in your own eye in order to see the speck in your friend's eye been as applicable as it is to those who today mock Mormonism for irrationality.
We would do a lot better to judge Mormonism -- and, for that matter, Judaism, Christianity, Islam, and the left -- by their fruits. And if we do, the religion of the Republican presidential candidate looks pretty good.
