For those who care:
Wicca is an earth-based religion that is centered around the respect of all things living.
Goddess is Great Mother Goddess. That is her name to me; usually I just call her Goddess. To others she might be Aphrodite or Kuan-Yin. She is in everything, in every person or plant or rock. You can speak to her and pray to her.
She takes many forms. She is the moon, and is often thought of as the Triple Goddess as manifested in the Maiden, the Mother, and the Crone. Her symbol is a full moon flanked by crescent moons. According to Wicca, there is both a Goddess and a God. (However, I only believe in a Goddess.)
The God is the Sun. He is the hunter and Green Man; the father.
Goddess and God-
Traditionally, the Goddess and God are lovers. They are equals. Almost anything can be categorized as either in the Kingdom of the Sun or the Kingdom of the Moon. They are in everything, according to tradition. Devil Wiccans in no way worship the devil. In fact, Wicca as a religion does not even believe in a devil. Although pictures of God or Goddess may have horns, this was normal in ancient times and was not a sign of evil. It was common practice for conquering religions (in this case Christianity) to demonize the gods they replaced.
Pentacle/Pentagram-
The point-up pentacle () is not the sign of the devil. The five-pointed star is called a pentagram, when inside a circle it is called a pentacle. The circular board that has symbols (such as pentagrams and triangles) carved into it is also called a pentacle. It is used by Wiccans as one of their magical tools. Hope that clears up all the confusion!
Laws/Rules-
There are not many rules in Wicca, but one that most Wiccans follow is the Wiccan Rede (also known as the Wiccan Law, Wiccan Rule, etc.): An it harm none do what thou wilt -- meaning, do what you want, but don't harm anyone. Another law some Wiccans folow is the Threefold Law or Law of Three. It is that what you do, good or bad, will come back to you three times as strong. Others believe in Karma, which is similar to the Threefold Law, except that what you give comes back equally as strong. Personally, I think this makes sense; what you give is what you get.
However, each person must decide for her or himself. Threefold Law, Karma, neither, or something different altogether?
These are the true Wiccan beliefs. Now, if you want to accuse them of worshipping Satan, many of them claim to be Wiccans, but are, as Alakazam so eloquently put it- "Pissed off goth kids who want to piss off their parents," or something to that effect.
Real Wiccans are ok people. Pseudo-Wiccans are stupid. People who chastise other people for their religion are stupid too.
