Greetings Eire
You have the right to call yourself what you want to call yourself. The point that I was trying to make in my post was that one should endure the fullness of their own traditions and culture.

Are there no indigenous Celtic traditions that the I can seek out?

If you truly knew self, then you would not try to co-opt a culture and livity that is not your own.

You would be perfectly fine revering your ancient ancestors, livity, and culture.

Like Garvey seh, "Every man to his own vine and fig tree...."
