I first thought this thread was troll bait... but alas. I skimmed over the article and walked away with two thoughts -
1. This is absolute rubbish
2. I wasted my time. Shame on me.

I cannot fathom how any experienced /studied practitioner could believe skin color, background, or sexual orientation would have any impact on a persons progress on the path. blood letting, cranial capacity, leaches, and voluntary trepanation are the domain tinfoil hattery.
The Buddha ordained women, dalits (untouchables), criminals, etc. These actions of the Buddha were confronted with hostility and anger at the time. Buddha dismissed the objections - to paraphrase a saying, "they are me, and I am them". What matters is the person - not what She or He looks like, or who their parents are, how much money they have or the cloths that they wear. Buddhahood is within us all -equally-, being white, brown, black, yellow, or purple with white spots makes no impact on the persons innate nature. To argue otherwise corrupts the very basic teachings of the Buddha.
