Communism Can't Kill The Faith

But Socialists will always try,  because they are a religion, a worldview that destroys opposition voices. 

"For generations, the Soviet Union closed churches and persecuted believers, and it mandated that all students at all levels of education receive classes every year in “scientific atheism.” As my late friend Andrew Greeley explained, the Soviet government “thought of itself as pushing forward the inevitable process of secularization in which religion would disappear from the face of the earth—a process which, in perhaps milder form, is an article of faith for many dogmatic social scientists.” This Soviet effort constituted a remarkable natural experiment. And what was the result? A national survey conducted in 1990, as the Soviet Union was collapsing, found that more than sixty years of this intense instruction had resulted in 6.6 percent of Russians saying they were atheists—only slightly more than in the United States!
Secularists have been predicting the imminent demise of religion for centuries. They have always been wrong— and their claims today are no different. It is their unshakable faith in secularization that may be the most “irrational” of all beliefs.”
