Now as to responding the calumny.
I find the whole concept of people being black or white troublesome. That's how our thinking is: black and white. Our skins are generally not those colors.
Now I have not examined the bodies of other women, but wouldn't they be the same? In other words, wouldn't women of other races have unpigmented, pink areas?
I tried doing a little searching online but found no relevant images. Medical images of vaginas that I could find were all of white women. Apparently my browser is protecting me from something.
