If they tear down all the statues of Columbus, they might as well tear down virtually every statue made of every historical figure before the last 100-200 years.
Few great historical figures were free of the sins many people prate about today as making somebody so evil their visages cannot be countenanced in public.
The simple fact is European exploration of N.America was bound to happen. Five hundred years ago and more there were few or no people who would measure up to today's standards of how people should treat everybody.
Columbus brought the advent of European civilization to this country. The Indians were mostly living in a stone age culture practicing many of the same things they criticize the European explorers for doing.
The Indians engaged in warfare, slavery, torture cruelty, conquering of other peoples....in short, they did everything the Europeans are accused of being evil for doing.
Except save for a few agriculural products (yeah, thanks for the tobacco, hack, hack), they've contributed little or nothing to world
civilization. They didn't even have the wheel.
So everybody shut up about Columbus and be glad he and subsequent explorers made it over here. You might all still be living in the stone age without them.
