Pride or Prejudice?

I have to preface this next part of my post by writing about a new game my kids have started playing...they started out by "calling" cars as they pass us on the road--each one of my kids tries to "call" the coolest car--which I guess means that in a perfect world somewhere far away, they have this secret stash of "cool" cars. The game has now evolved to include anything and everything--the other day, Tessa "called" the Oquirrh Mountain Temple--after which we promptly had a lesson in the car about reverence for sacred things :).
So, keeping this game in mind--the following conversation actually took place :
Christopher: "I call all the food in the world."
Carter: " Well (pronounced wool) bud, some of the food in the whole world is gross."
Christopher: "Then I'll just give all the gross food to the Indians."
(he looks around as though he realizes that statement is somehow wrong--then stammers)
Christopher: "I mean the Utes--ya, the Ute Indians."
I was, of course, laughing hysterically (trying to be quiet) in the front seat. We had just had a conversation about mascots and what a Ute was--we are big-time BYU fans at our house and have thoroughly indoctrinated our children--so Christopher had just learned that the Utes were a tribe of Indians that are a part of Utah history--and that the University of Utah has named their mascot after them.
So now as mother, what do I do? Is he just declaring his loyalty to the Cougars? Does he have some racial biases that have been suppressed until now? It's hard to know sometimes what exactly goes through a child's mind--he's definitely heard his father declare all out hatred for "the Utes"--how is he to interpret that. So, in wanting to please his father and "outsmart" his older brother in their new game--I think he'd probably say it's a little bit of each--perhaps both pride and prejudice.
