Although I don't take too well with people who are Satanists, I will say that you are still human. You're no alien. You're religion or what you practice should mean nothing to no one.
From what you said in a post, I know for a fact that you are a good person. You don't want to harm others and I respect that fully.
I suggest you go through the basics of Wicca. Find out what we do, what holidays us Witches celebrate, find out our customs. You start from there.
