You clearly don't understand this, but there's a wide gulf between the facts and your opinions about them. Your opinions is that the facts can be interpreted to make Columbus out to be worse than Hitler, but my opinion is that the facts make it clear that he's not only not in the same league, he's not even playing the same sport so there you go.

In order for your dumbass example comparing these two utterly unrelated things to be true, France, England, the USA, and every other first world nation would have to have been engaging in behavior equally egregious to the holocaust perpetrated by Nazi Germany.

Every imperial nation was engaging in colonialization and the slave trade, but JUST Germany had Nazis so FACTUALLY, your example falls flat on its face.
