In many parts of the country, Columbus Day has been re-named Indigenous People's Day. I've studied extensively on the treatment of the Taino people by Columbus and his men, as they all but wiped out the Taino race. I must admit that many indigenous people in America died of diseases caused by people and animals coming from Europe--that couldn't be foreseen or understood at the time. Working people to death, being forced to mine for gold for the Empire, however, was inhumane and not an act that can be forgiven.
The documentation of this slaughter is plentiful, and beyond dispute. This is not a political opinion, or a personal agenda. Historical fact.
