It's sad that Hadiya's dad told her that the old lady on the subway didn't like her because she is black. That might have been true, but it would have been more accurate to say that some people don't like others because they look different. No one is immune to discrimination based on appearance, e.g. racism, which arrises from ignorance and fear. Unfortunately people from visible minority groups are much more likely to experience racial discrimination, by pure statistics. Everyone should be aware of this.
