Why shouldn't Americans celebrate Columbus Day?

Answer 1

With regard to the fact that he represented the takeover of the Americas by European races, Columbus and all explorers were detrimental to the cultures of Native Americans.

However, the current nations that exist in North and South America would not exist, and the world would not have benefitted from them, if not for the pioneering voyages of Columbus.

Answer 2

If you mean "North Americans", a reason might be that he never discovered, let alone set foot in North America. North America by rights should celebrate "Leif Ericson Day" because Leif discovered and settled in North America some 600 years before Columbus - who only discovered the Caribean Islands and never ventured further to America's mainland.

Columbus by the way remained to his dying day firmly convinced that he had discovered a part of the coast of East India, even when others were already certain that the islands were part of a "new world".

Finally, Columbus turned his Governorship of the recently discovered islands into a reign of terror, to such an extent that the Spanish Government had him arrested and transported back to Spain in chains.
