Even critics of Crenshaw have given her credit for pointing out that a company could have policies designed to help women and policies designed to help blacks that could be implemented as designed without helping black women. She wasn't wrong. The problem was when the model of intersectionality was expanded far beyond its original application.

It's like the concept of safe spaces. The idea of a safe space was originally conceived as a way for college professors to let gay or lesbian students know that it was "safe" to talk to them in their office about issues they were facing, back before campuses had other resources for these students. In the 1990s, it made sense. You could get a "Safe Space" sticker for your office. Then it was expanded to the classroom and eventually to the entire campus as the idea that no one in an "oppressed group" should ever be exposed to an idea they don't want to hear. And people can go into hysterics and claim that the mere presence of someone who holds opinions they don't like makes them "unsafe." It's a complete perversion of the original intent.
