Ah, yes - the Church of the Latter-Day Druids (or whatever they call themselves) is one of my favorites also. Especially since what little we know of the original Druids comes mostly from Caesar's accounts of tromping around Gaul. And he had almost nothing nice to say about them - I seem to recall that one of their preferred methods of predicting the future consisted of boiling a man alive, and interpreting his screams as he died. I don't hear about that one much anymore. Maybe they've retired it ;)
Maybe they've retired itFunny thing about the Romans. They were remarkably tolerant of other religions. Pretty much as long as you didn't practice human sacrifices or try to convert your neighbor, you were OK. If you did one of these things, they suppressed you.
The Druids got suppressed but good, for the one reason, and they attempted to suppress our Christian forebears for the other.
