Don't worry about starting here. I didn't understand at first either. It was also going against everything that I grew up with and was taught. But I also found out that what I had been taught was only half of the story. I decided to do some research myself, and have found my place in Wicca. If, after some time, you feel it is not for you (some don't), don't worry. No one is going to disown you, threaten you with hell, etc.
I would recommend that you start out by reading through our "newbies" page, it contains all of the info that you will need to start out. If, after reading through, you still have any questions, there are plenty of people here who will be more than happy to help you.
