This is a great article! In my opinion, Columbus Day is inappropriate with the information we know.
You cannot discover a place where people have been living for centuries just because it's the first time you, or your friends, knew about it. By this logic, I could discover and take a watch from someone's wrist just because it's the first time I've seen it. Of course, we wouldn't do this because it's stealing, that's exactly what happened to the indigenous people of America.
