Pentagram

Like what most already have said, it is best to explain why you wear it. It I go around wearing a upside down pentagram than I can understand where they are coming from, but an upright pentagram I try to explain that my believe is different from your believe.

Sadly there are people that look at us as "evil" so they can feel better for themselves for being "Good." Those are the kind of people that will not listen, but there are not that many I come across.
