Remember the good old days when Black got you 5 points and Gay only got you 3 Points?
I see that you have not been tutored in the mysterious ways of Common Core Math, Grasshopper!
These days there are 57 Varieties of "Gay" whereas for "Black" you have a much narrower spectrum ranging from Idris Elba & Whoopi through Bill Cosby, OJ, Obama and Rachel Dolezal.
Since we aim for Diversity ("Ommmm", "PBUH") these days, the wider the spectrum, the more points!
Simple, really!
