I've been reading a bit of The Apple Branch by Alexei Kontratiev. I like the fact that he says that the Celts have been Christian for centuries, so it's kind of silly to be into Celtic stuff but be anti-Christian. But then I don't like where he goes after that. He defines Tribe as people who speak a common language. Then he goes on to say therefore, if you are interested in Celtic stuff, you should learn a Celtic language. I would think that the same logic he used with regard to Christianity would apply here --for many Celts, English is their native language now.
I don't like it when people get fixed in their mind that one particular moment in history is the correct one, that the people who lived in that place and time are the true natives of that land, and anyone who came after was an intruder. The reality is that human history is a history of migration and cultural change.
Some of my ancestors came to North America from England. Some take the attitude you English should not have come, you should go back where you came from. But people from England, they had ancestors too, they had Angles, Saxons, Jutes, Celts, Romans, Normans. Yes, at one time in history some of my ancestors lived in England, but they lived in other places before that, and they lived in New England after that. Why pick on England as the place where my people are truly from? That kind of thinking is a narrow view, that does not grasp the way cultures shift through history.
