Probably because they know niggers. Even if you avoid the feral ones there are those that attack without warning and those that pretend to be a good friend yet rob you blind when they think they won't get caught.
Most "minorities" are people you should stay away from. Not all though. Its just a pity your father didn't trust your ability to judge good from bad on your own or perhaps he judged the entire group collectively due to the traits of the majority.
