Oy, this thread got busy. Not as crazy as a couple days ago, at least.
First of all, the Wiccan Rede is NOT The Golden Rule. It doesn't say anything about how you want to be treated. When combined with the Rule of Three, MAYBE, but not with it along. The Wiccan Rede is ADVISING you to harm none (not JUST harm none, but it's very roughly shortened, don't try to say it's "harm none"), the Golden Rule tells you to treat others how you want to be treated. The Rede is just a piece of advice, advising you to harm none, it doesn't say anything about doing good. The Golden Rule explicitly TELLS you to do good (or bad if you're a masochist I suppose
).
By the way, I believe that every god and goddess has aspects, or rather is a "facet" of, the God and Goddess. So basically, when you worship X other god(s), you're really just worshiping certain aspects of the God and/or Goddess. It's not strictly wrong, but it's not the whole "truth". In other words, every religion (and even atheism) has elements of truth to it. It's a strange concept to wrap your head around, but my opinion is that people pick and choose their gods, and I just chose the "right" ones.
I'm not going to try to convince anybody though, Wicca is very strong on personal responsibility, so you'll figure out what's right eventually, on your own.
And now do you see what I mean by unnecessary conflict?
