I remember kid parties where the children were to dress like characters from the Bible. Many characters were loyal servants of Jehovah who spilled generous amounts of gentile blood to clear out the promised land. That was ok.
I remember a party where we played Bible charades. When it was my turn I conscripted the youngest children as possible and my brother. I was Elisha. The children were children. My brother the bear. As my brother pretended to maul the small children all the adults laughed.
I am so glad we never went to one of the those awful pirate parties.
