Not necessarily. Marxism and then a brutal dictatorship totally destroyed the nation. Before that, blacks and whites got along just fine and I experienced that first hand.

They did have a say, and their country was transformed into a peaceful and productive paradise. Marxist theology came later to destroy everything they had achieved.

"Rhodesia" didn't exist until white people showed up, but there were blacks there before. Shouldn't they have had a say on what their future should be?

So Rhodesia should have remained under colonial control by white people...is what you're saying?
