I guess there might be a misconception there, since Wiccans spend a lot of time celebrating fertility and the like, but no, Wicca is not anti-condom. As a religion, it's actually very much geared to the left. It's not often you'll find Wiccans who are pro-lifers or who enjoy voting for the Conservative party. It draws heavily on older Celtic religions. The whole thing was thought up by a hippy and author from the early part of the 20th century (
Gerald Gardner), but as a means of expressing spirituality, I think it does its job well.
My mother is doing a Ph. D in Sociology of Religion (she's focusing on Catholicism), and has read about Wicca in some of her academic jounrnals. It's actually true that the number of people who identify themself as Wiccan spikes every time some form of popular culture involving the occult comes out (including Harry Potter or Buffy the Vampire Slayer, of all things). It's also true that lots of people go into it for the sexuality aspect. But it's fun all around, and there are varying levels of belief and followings in the religion.
One of the people I remember from my youth-times is
Sam Wagar, who was pulled out of an NDP riding in British Columbia after it was discovered he was a practicing witch. His kids got me into roleplaying games and forum roleplaying.
I haven't gone to any of the Gatherings (large events where all the pagans - including Wiccans, Norse Pagans, and other Celtic Pagan types - go to meet for a weekend every summer) in a few years now, but they were always great fun, and there were lots of nice people. I've picked up some talents like reading Tarot Cards, as well, which is always great at parties.
My father is a non-practicing Catholic, and my mother's parents and grandparents are all fairly devout Christians. She was raised Pentacostal.
