Whether the school’s administrators would be welcoming is one thing. I think the more interesting question is whether the school’s students would be welcoming, and the answer isn’t obvious to me. I would assume these days many students at HBCUs have other options but chose a HBCU in part because they value their own black identity and certain aspects of school’s distinctively black history and culture as well as certain aspects of black culture more more generally that might be more mainstream at a HBCU. I know a few white students do attend HBCUs, but I wonder whether there might be a tipping point at which some black students might think too many non-black students would undercut some aspects of the school’s identity and culture that they value. I really don’t know the answer to that.
