Clown is a banned name? I'm sorry, but that's a bit weird. Even though it could have a negative connotation behind, that isn't always true and it certainly isn't offensive. After all, clowns are supposed to be happy and entertaining. Perhaps "Pogo the clown" is offensive, but not clown. I don't know. Not saying it's a good name, but I don't agree with banning names.
I don't care about people naming their children after religious figures. Just because it's sacrilegious to some doesn't mean it is to everyone.
By the way, has anyone tried to name their child after Pogo the clown? After mentioning it, I imagined some really sick and disturbed parents out there. Pogo T. Clown or something I suppose. Now that would be scary and tragic for the child.
