Not sure of the OP’s sensation but when an institution creates highly visible programs supporting every single group except one, then it is a form of exclusion (albeit a negative form vs a positive form of exclusion). You could say that such policies are necessary or justified to redress historical inequalities. This is the traditional justification for such policies. Such an argument starts to break down over when those inequalities are less noticeable.
