Or so says a U of Penn professor: http://www.amren.com/news/2013/06/ms...ing-whiteness/

So I think that there’s a kind of moral panic, a fear of the end of whiteness that we’ve been seeing a long time in that I think, you know, Obama’s ascension as President kind of symbolizes to a certain degree. And so I think this is one response to that sense that there’s a decreasing white majority in the country and that women’s bodies and white women’s bodies in particular are obviously a crucial way of reproducing whiteness, white supremacy, white privilege. And so I think it’s just a kind of clamping down on women’s bodies, in particular white women’s bodies, even though women of color are really caught in the fray.
Everything is race with these people. Pretty soon you can't say you don't like chocolate because of racism.
