I should probably insert "authoritarianism" in there somewhere, but my point is that your connection is patently proven false by history. If socialists believe all cultures are fundamentally equal, why did we have a Cold War? There would be no reason for the Iron Curtain to descend and for there to be 40 years of rift between the Soviets and the West if they fundamentally believed all cultures are equal.
No, you don't...
