Why are you surprised that Texas fans hate OU and don't want them to win? Nothing childish about that at all. Eff OU!
That's cool MM and totally fine with it (not that you need my confirmation, lol). I have many friends that are UT fans and don't like OU either. But like I said in another post: I am praying so Hard to Sweet Baby Jesus that UT takes UGA to the woodshed in the Sugar Bowl. I very rarely pull for UT (pretty much only when a UT win benefits OU), but my hatred for all things SEC way outweighs my hatred for UT. I know there is no way many of you will pull for OU, that's fine and completely understandable. Good luck and Hook em'!
