Walter M. Kimbrough, president, Dillard University writes: Like so many cases over the past four years, beginning with the protests at the University of Missouri at Columbia, I have seen numerous instances of students demanding that their institutions, and particularly their presidents, do something to end racism, diversify the faculty, provide safe spaces, etc. Uncomfortably I’ve watched video of students’ yelling at and berating their presidents for not doing enough to immediately remedy America’s original sin.
