Completely incorrect example. The Nazi situation was a majority accusing a minority. You could say Mugabe is like H, or the KKK are like H .
Does being a minority make it OK? There are many examples of minority populations who oppress the majority -- does that make it right because they are in the minority? If the black population in the US becomes greater than 50% does that mean that our black racial warlords are then like Hitler but not before?
