You don't think colonialism "screwed the masses"?
But is Mugabe in Zimbabwe any better?
It's very political correct to say "Oh, colonialism! That was bad, wasn't it?"
It is less politically correct to say "African dictators have really botched up that continent, haven't they?"
I'm not in a position to say one is worse than the other. I just say that the "evils of colonialism" are not necessarily unmatched by current native systems.
