The people were many other things, not Celts. That word, celt, comes from one specific group, and has been used as an umbrella term for a long time.

Also, I am a mutt. My other half is gypsy, which means literally a mixture of everywhere my gypsy ancestors wandered. Lots of French, Spanish, and Iranian, unfortunately.

I don't have a problem with the term celt being used, but it needs to be made clear that it is literally a word that is used to group in a bunch of different people....Just like the term "Native American". I hate that term. Natives to America?

America is Rome. I'd prefer to refer to places in America by State, and the Natives by their actual people group.

They were all so different, and anyone who tells you otherwise is a brick. I've met so many different kinds of Natives, and some are indeed psychopathic alcoholic whiners (just like some white folks I know) while others are proud to be who they are, and they know their own history better than some biased fool.

There was human sacrifice happening in some Gaelic speaking tribes, and in some Native tribes. To try to say they all did that is a fucking lie.
