Children and Ultimate Fighting

If we have outlawed things such as Dog fights and Cock fights, why are are we so reluctant to outlaw 6 year olds participating in Ultimate Fighting? Is is because there is no money exchanged during betting hour, or is there? What are we thinking? Everyone thought allowing children to watch Bugs Bunny and the Road Runner challenged brutality and increased violence in children, but what about this new phenomenon? My wife say, "Some parents are just idiots." I agree totally.
