I don't know if you have expressed your specific support for affirmative action on this forum, but the fact that you do support the continued existence of black colleges is proof enough for me. Historically (or whatever they are called) black colleges ARE a form of affirmative action. I know you will disagree with my take on it, but that's my opinion.
BTW. has the period referred to as black history month outlived its usefulness?
It's illogical to assume that someone who supports historically black colleges would automatically support affirmative action. HBCUs are not affirmative action- they get little or no special money or programs just because they are black. HBCUs do not discriminate by race- white applicants to them (yes, there are some) get the same consideration as anyone else. Graduates of HBCUs get no special breaks in the job market compared to blacks who did not attend HBCUs.
As long as there are people who believe as you do, Black History Month will always have a usefulness. You need it much more than I do.
