Are there any peer reviewed scientific articles that prove those assertions. I found James article vague on definition of terms and not quoting enough research. Not to mention the fact that extrapolating from broad population averages to a specific set of people who are not representative of the population will make the evidence for the population inapplicable to the sample in question. Having said that, I don't think firing and lynching was the right response, it just encouraged extremists on all sides.
