A classic example of "that was then, this is now" for partisan political purposes.  The questions for today are HBC/U's really about inclusion or exclusion?  Are their diploma's competitive?  Should we be making efforts to increase the non-black populations in them?  Are we artificially keeping some in existence (massive subsidies)?  In short, are they still needed?  Below is a list of HBC/U's in just North Carolina and when they were founded:

Barber-Scotia College (1867)
Bennett College (1873)
Elizabeth City State University (1891)
