Yes it is "still a thing". They are mentioned in legislation as Black Colleges. It was an extremely big deal this year when Black Colleges were successful in lobbying for Title III funding. In fact, they are listed officially as Historically Black Colleges and Universities (HBCUs). Native American's higher education institutions are referred to officially as Tribal Colleges and Universities (TCUs).
Wouldn't focusing on fixing this situation be more beneficial than reinforcing it?
So, yes, that is what they are referred to in legislation, so stop trying to imply someone is not using the right words. It really ticks me off when people wordsmith but don't bother actually engaging or knowing any of the history of the people they are being offended for.
Maybe if you stopped implying racism where none exists, we would have a better world.
