These "facts" are not true at all. Facts about Columbus, to start. He was arrested and sent back to Europe for being a Barbarian, but it was all proven to be false. The Barbarians were those who were in his employee who didn't like the way he governed the natives. He did NOT let them take advantage. It goes to show how long a terrible lie can be propogated.
If I know that one "fact" to be a lie, what is left to be believed?
