It's true that people do have thin skin, especially in circumstances like these. You don't see what's offensive about it? Well, when your race is put into slavery for over 400 years, then endures more torture and killings at the hands of the Klan during the Jim Crow law/civil rights era, and still has trouble being seen as equals in many aspects of life, then you'd understand a bit more. Not saying that I am that thin skinned on race issues, but there are plenty of black people who are, and for good reason.
