What is Columbus Day's alternative name?

Answer 1

I have researched on the Web and found one suggestion put forth by a Native American Action group, "Indigenous Peoples Day"

It is very apparent that Native Americans are extremely offended by the celebration of a man they consider to have not discovered, but merely encountered the lands of The Native Americans. They see that his encounter resulted in the spread of disease, the theft of Indian lands, and the Europeanization of a native land.

Most Latin American countries and cities with large Latino populations often refer to it as Día de la Raza, in many countries is seen as a counter to Columbus Day. It is used to resist the arrival of Europeans to the Americas and is used to celebrate the native races.
