There is no proof he did that. You are just repeating liberal propaganda you heard against him. Please encite actual historical evidence that Columbus commited these atrocities you claim. He brought plumbing and civilization to the natives. If it wasn't for him, most of the world's Hispanics would not exist: 80% of them are a mixture of native and spanish blood. So, by defaming Columbus, you are insulting Italian Americans by the vicious slanders that you go against him. That is hatred against these Italian Americans, which make up 10% of the population, and Italian Canadians, which make up 6% of their country. Columbus is a great man. Leave him alone.
