Whatever meaningful socialism there was in _______ was wiped out during ________
1) the USSR / Stalin's purges

Socialism / Communism isn't a way of running a society. It is a method used to disrupt and destroy a society. The nuances and differences between socialism, communism and Progressivism are as meaningless as the nuances and differences between the effects of different types of nuclear weapons on a city. Socialism, Communism and Progressivism are a means to achieving totalitarianism, no more, no less.
