Pentagram vs Star

Michelin is a witch, I describe in detail how she sets up to do certain spells. I had used the pentagram the usual symbol that witches and wiccans use in their spells.  Yet their is such a stigma with the pentagram that I am taking it out and describing another star. My book will be geared towards young adults. While I do understand that they grow up so much faster, after working in Barnes and Noble for two years, many parents didn't mind the mystical side of stories involving witches, vampires etc...They didn't like the "unnatural, or evil" side of the mystical. While this is not my personal belief, I am conforming to mainstream. I hate that I feel like a sellout, but I do want to get published.
