ELI5: How come "only blacks school" is not racists toward other races as would be "only whites school"?

It is racist. And the only-black schools were ruled unconstitutional some 60 years ago.

Now, there are some "historically black" colleges that were established as black-only colleges in the days of segregation. Today, these schools have a racially open policy while attracting a predominantly black student population.
