Whittaker Chambers was, to coin a phrase, there at the beginning. His communism was genuine and at the early stages in America. He certainly had the credentials to answer the question he posed for himself, why?
His answer was essentially that communists were communists because they would be God. God players do not find themselves constrained by the rules, Gods make the rules. So the very seductive siren of socialism offers easily navigable ground for the nimble man become God to rationalize every brain fart for the benefit of society and, equally, to rationalize and trivialize all the misery they cause.
Communism therefore is not essentially a manifestation of a misguided intellect but a spiritual cancer and the cure, therefore, cannot be to persuade the would be God with reason but to offer him an epiphany and a new birth.
A new man, as Whittaker Chambers became, finds himself very much in alignment with reason.

Be like the most high. I’ve read that somewhere.
“And ye shall be as Gods.”

Communism depends solely on the premise of “If man is left to his own devices, he will default to doing good” which is simply not true. Workers never controlled the means of production in the Soviet Union. It was controlled by dictators. Communism and Socialism are just a pretty way of saying Dictatorship.
Liberals have always accused social conservatives of bringing religion into politics, but liberals have done something far worse, and far more radical: They have made politics their religion...What they really want is liberal Sharia law, a secular theocracy.
The minimum wage, gender equality, nationalized health care, and global warming—whatever their practical virtues—are not just expedient policy prescriptions. They are essential aspects of the liberal fatwa. Feminism, deconstruction, and gender theory are not just academic abstractions up for discussion among liberal academics: They are articles of their religious creed. Question them and you are not just wrong—you are a heretic.
You wonder why the left is having a nervous breakdown in the wake of Trump's election? It is because, for them, politics is the means to secular salvation. This means that, to them, political failure is not just a setback on the road to a more stable society—it is a blow to their very worldview. Opposition to their program is not just wrong-headed, but evil.
This is why all of the excesses of these demonstrations—death threats, looting, violence—can be excused by CNN and MSNBC: They are the necessary extreme measures, justified in light of the threat to their ideology.
