I trust you find Twyman to be a questionable source who speaks out of both sides of his mouth.
From your link:
"To their credit, some African-American law professors rejected the siren call of the pied pipers at Harvard and UCLA. Professor Stephen Carter at Yale became a well-respected scholar of constitutional law with an emphasis on Separation of Powers and Religion.....Professor Barack Obama at Chicago focused on public service and became U.S. Senator from Illinois. The African-American community has been well served by their work."
"After graduating with High Honors from the University of Virginia and Harvard Law School, W. F. Twyman, Jr. worked at a major New York law firm, served on the staffs of Congressmen Barney Frank and Henry B. Gonzalez, and taught as a law professor for seven years."
I found his comments on Critical Race Theory interesting.
