Today we honor the man who didn’t discover America. The Native Americans obviously discovered it first. Then Vikings, Chinese, and maybe others arrived. Columbus never even found the North or South American continents; he only landed on some Caribbean Islands. What he did do is begin the invasion of the Americas by European Christians. These were soldiers accompanied by priests. That way, when they were done torturing, enslaving, infecting, and killing the indigenous people, they could force the survivors to adopt Christianity.
Ferdinand and Isabella, the rulers of Spain, having driven off or killed all the Jewish, Islamic and other non-Catholic people, needed someplace new to spread Christian love and charity. Thus began centuries of religious bigotry, holy wars, destruction of native cultures, and ethnic cleansing, as soldier and inquisitor marched arm in arm across the land. Praise the lord and pass the ammunition.
