Antonio Gramsci taught that Marxism cannot succeed until Western Civilization has been reduced to rubble. The destructive urge is a creative urge. So destroy all the things that people love and depend on, and in the years, and decades, and centuries will follow such destruction, you can try to build a worker's paradise without the distractions of government, church, marriage, or families.
Chief enemy of Socialism is always God because He teaches us moral values and the worth of the individual.
...and of course, the State cannot tolerate something which is more powerful than itself - the State is God and all must bow down to it.
Under Socialism, that which is right or wrong is whatever the State says is right or wrong. Eric Blair - aka George Orwell - recognized this very clearly in his books 1984 and Animal Farm.
