Marxism, means people will turn on there beliefs, over a whim ?

It's all about indoctrinating the art of DoubleThink (ala Orwell's "1984"). How someone can have 2 contradictory and opposite thoughts coexisting in their mind: War is Peace. Freedom is Slavery. Ignorance is Strength.

Marxism means failure and people quickly ending up in an oppressive dictatorship..
