I found this, i like it.
Perspectives:
Tell me about the origins of your concept of intersectionality.
Crenshaw:
It grew out of trying to conceptualize the way the law responded to issues where both race and
gender discrimination were involved. What happened was like an accident, a collision. Intersectionality simply
came from the idea that if you’re standing in the path of multiple forms of exclusion, you are likely to get hit by
both. These women are injured, but when the race ambulance and the gender ambulance arrive at the scene, they
see these women of color lying in the intersection and they say, “Well, we can’t figure out if this was just race or
just sex discrimination. And unless they can show us which one it was, we can’t help them.”

It does seem to be different to the views attributed to self-called intersectionalists in this thread.
