Victim? The joke was that they persuaded them to be racists.
edit: you should leave it alone, though. People only move from mad because they misunderstood the joke to even madder for you not making the joke easier to get. They won't relax if you keep digging.
Once again, please stop insinuating things that are a. untrue and b. you cannot possibly verify (were you in the uber rides with me?) just because of your preconceived notions and biases that you'd like to be true.
it's just a joke...
