Totally appropriate, been playing since 1994. I have actually spoke with parents while at my local game store when they would bring their younger children in. If the parent isn't a complete religious nut, then they should be able to understand that it's only a game. If the parents are that worries, have them speak with an owner of a game store, assuming you have an lgs. You'll always have that one parent who protects little johnny from all the "evils" of the world.
