Why do Witchcraft and Wicca always seem to go hand in hand?

I have been trying to read about Witchcraft on this site and been trying to gather information, but it seems like immediately when someone mentions witchcraft, wicca always comes up in conversation. I know Wicca is a religion that practices magick and Witchcraft is not associated with any other religion/belief, but why do they always seem to go together.If I am interested in Witchcraft, what resources/books are good to read? Are there any beliefs besides Wicca that I could/should become knowledgeable about? ------

It is common association. People do this with all groups to some extent. They associate Mormons with having many wives (unually underage now,) they associate Athiests and Chrisitans with hostle ignorance and arrogance aimed at each other, they associate Democrats with increased taxes and Republicans with spending money they do not have, they associate Muslims with terrorism, they associate soccer moms with a finatical sense of competition and blond women with a lack of intelligence.The list of these associations goes on and on and, it is largely because it is far more easier to patronize someone or a group with these common associations than it is to actually try and understand any single individual. ------

People just don't no any better.Not all witch's are wicca and not all wicca are witch's.There not even close it goes much deeper then that ------
