What part of it's Columbus Day don't some folks understand?

As most of you know, today we celebrate Columbus Day.  Not Native American Day, or Indigenous Day.  Sure some have changed the day name, but why?  Columbus Day never was a Holiday about one race conquering another, but some seem to make it that.

It's a celebration of  where Europeans found out that there were other people out there beside the Europeans and Orientals. I was told that we all are Native Americans now and I'm all for that.

If the Indigenous Americans want a day of celebration, that's fine.  But don't take Columbus Day and make it something that it isn't.

What say you?
