I don't understand what you're arguing. Equal opportunity will lead to diversity. Equality is about removing processes that look at privilege (e.g. your rich father donated X dollars so welcome to our college).
If your idea of fairness requires we become systematically biased against certain majorities (white, heterosexual, male, cis-gender) for your cause then I don't want to be part of your cause, and moreover I find that cause discriminitory and dangerous.
