I think intersectionality is one of these bad ideas. And it's not all bad. I mean, there are certain experiences that say a black woman is more likely to have than either a black person or a woman and that the sum of those identities don't add in a linear way. It seems to me from a perspective of a social scientist that intersectionality may be a semi-dPT. There's something about being a black woman that adds up to a disadvantage that is not just given by the arithmetic sum of the disadvantage of suffered by black men on the one hand and white women on the other hand.
