The answers are so beautiful and this is so very thoughtful. Wicca is a recognized religion in the United States since 1987 and was likely founded in the 20's or 30's by a uh... interesting guy, Gerald Gardner. I make it a point to educate myself on various topics, like the old days. It's amazing the things you can find books on nowadays, informative and otherwise.
I was once a Wiccan. I still think it's a beautiful thing-and harm none is more strict than you might think. Gossip for example: it does hurt people eventually. It forces them to think long-term. People have told me many times in the ten years that Wiccans are the most polite, considerate people they know. Pagans might inform, but they aren't looking for converts-in fact, most recognize that Wicca/Witchcraft/Paganism is not for all.
This is a most excellent resource on the matter for those who wish to educate themselves without delving into the weirdness that is Wicca. This sort of reasoned conversation is so much better than what I expected.
I am a Christian now, but I have utter respect for them. If Wicca taught me anything, it is reverence for all creation-after all, God made it, didn't He? To wit, what convinced me to turn back to Christianity was this: Wiccans many times acknowledge that their God and Goddess are but two faces to some higher, unknown deity. Does that sound familiar?
