personally i thought gorgan's avatar was harmless, but then thats a male's point of view. if the female's point of view is thats it's offensive then we must respect that.
also i realise that if this avatar was allowed then the problem is where to draw the line.
if you rule it all out then there's no room for argument. but if you allow this, then its human nature for people to see how far they can go bending the rules without breaking them.
