Now one must appeal to attributes of groups which are abstract rather than perceptible. Poverty, crime, high death rates and faulty English remain useful to the task but more about these in how to use sociology later. Secondly, Physiology is a good marker for the compleat racist. Sickle cell anemia, glucose intolerance, immune system deficiency all make good talking points to those who want to hear the message. And, there is no talking to those who don't want to hear our racist theories so go ahead and make good use of them.
Sociology is a god-send to good racists.
It provides both theory and data with which to make a case. Labeling Theory can be used since it doesn't bother to ask why people deviate in the first. And Merton's Strain theory is so vague that no one can use it for anything but the fuzziest of generalities. So the good racist can simply say that failure to conform is due to racial defects and female incompetancies. And, fortunately, Conflict theory is so thin and watery that anyone could handle objections that racism is bad for a society.
