Mainly, because Christopher Columbus was a massive cunt.
Let's set some things straight.
1. Columbus did not "discover" America.
First of all, Columbus did not set foot in North America. Never. Did not happen. He explored the central and south American coasts, and only a tiny bit of those, and landed on various Caribbean islands. Leif Erikson discovered North America. 500 years earlier. Columbus has nothing to do with the existence of the United States of America.
2. Columbus was a massive cunt.
Besides being a gold crazed lunatic, that is. He required that all natives in this new world, natives he called pig-nosed savages and whom he said would make excellent slaves, mine gold for him. If they refused to do so, he would remove their ears or their head, depending on his mood. If they accepted they were given quotas to meet. If they then failed to meet said quota he would cut off their hands, tie them together, and hang them around their neck while they bled to death. It's estimated that he did that to some 10,000 natives.
3. Columbus sold little girls as sex slaves.
This doesn't need anything but a quote from Columbus. He wrote this in the year 1500:
“A hundred castellanoes are as easily obtained for a woman as for a farm, and it is very general and there are plenty of dealers who go about looking for girls; those from nine to ten are now in demand.”
4. Columbus sold natives as dog food. Seriously.
Taken straight from this article:
On his second trip to the New World, Columbus brought cannons and attack dogs. If a native resisted slavery, he would cut off a nose or an ear. If slaves tried to escape, Columbus had them burned alive. Other times, he sent attack dogs to hunt them down, and the dogs would tear off the arms and legs of the screaming natives while they were still alive. If the Spaniards ran short of meat to feed the dogs, Arawak babies were killed for dog food.
