Is intersectionality threatening French sociology (and sociologists) of social class?

Since the translation, in 2005, of one of Kimberle W. Crenshaw's articles introducing intersectionality into the field of French social sciences, the word and the theoretical perspective it labels have been the object of great mistrust on the part of many sociologists claiming a critical position. The lexicon of threat is mobilised to disqualify the intersectional approach - much more than to discuss it - because its aim, or effect, is to purely and simply erase social class as a fundamental category of analysis. The article goes back over the reasons for a trial that has become more and more noisy over the years, made of maintained ignorance and refusal of controversy.
