You know how some girls sign the i's in their names with hearts? Well sometimes I sign my i with a pentagram. Being an atheist, I find it ironic and amusing and couldn't care less what people think.

This IS America. Freedom of speech/expression was what this country was supposed to be based off of. If people express themselves in a manner that may be deemed controversial in a way that is non-invasive then there is no problem or issue. Just people getting their feelings hurt. People in general need to learn how not to get so pissed off at these sort of things.

If your son draws pentagrams, then let him draw pentagrams. If your son gets up in somebody's face just to see their reaction to something they might find offensive, then I'd slap him across the face.
