Hehe, it's okay Evilyn a lot of people have asked. There's no great way to do it other than to remove the thief cost for all races from the race details page. It probably doesn't need to be there since it does not vary from race to race...however I imagine after that people may complain the '50% thief cost' doesn't provide much information if you don't know what base thief cost is. It's a tough situation to please everyone regardless but RattleHead is correct.
