It really depends. I have owned rott's, one of which was the daughter of one of the rott's from Lethal Weapon (3 I believe?). Anyway, if a rott has seen violence come from one particular race, you(or previous owner) change tone or demeanor around a particular race(if you distance yourself, change from happy to neutral, etc.), or a new person with an odd smell (personal odor smells different from other people you are usually around) comes into the animals/your personal boundary without greeting or in a shady manner, it may be partial to aggression towards that race/person.
I trust my current Rott as a better judge of character than myself, she won't let anyone in my apartment if they are high on anything or extremely intoxicated, won't allow new people in any room other than the living room, dining room, or restroom. She is apparently nice to everyone, except for once when my buddy brought 2 friends over - she immediately growled at them when they tried to come in. Three weeks later they were both arrested for theft.
Don't punish her for being apparently "racist", just try to bring her/him around a person you know well of that race and allow her to smell them and know that they won't cause you any harm. I highly recommend a leash for this excersize - us rott owners don't want any non defensive attacks to make the reputation of these lovely animals any worse than it already is... That is of course, just in case, as I have never met your particular pet.
Kudos, and good luck!
P.S. My first rott was racist against "African Americans", as the breeders that I received her from were, and I got her when she was just a small puppy.
