I think, despite all protestations to the contrary, that because nothing beats ES chasing trolls race bait with the same old canned rehearsed reactionary replies is what they really like.
Being pro-active and researching Egyptology, African Studies, etc., and presenting the results in a positive narrative form is just too hard for them.
We'll see if TNV is around for when Black and African students want a place to present their studies, finds, and hypotheses for respectful comment and critique from their peers. If so they will buck TNV's URL around their BSU, ASA, and study fields department bulletins.
Don't hold your breath I doubt there's any interest or there would be such interactive sites with a popular though academic bent to them out there already.
