What does it say about a country to support a person/holiday such as Columbus?

In opinion, I believe that for a country to support a person/holiday such as Columbus, is like a bunch of pet owners giving a dog a treat for slaughtering cats. But even though Columbus treated the Native Americans unfairly in their own homeland, America probably would not have been found, and I would not be where I am today.It is a great idea to have a celebration for the founder of America, but unfortunately some people do not realize that Columbus did horrible things to the Native Americans who had been living there. 90

I am not against the celebration of the founder of America, but nothing can change the fact that the Native Americans were actually the "first founders" of America. 28

The country should celebrate Columbus Day because Columbus found America, but the nation should also acknowledge that Columbus was not heroic for killing the people in their own homeland.
