One of the tactics used by Chevalier in this conflict, and which Coraline Ehmke has also used in some of her online discussions, is to redefine "biological essentialism" to cover all discussion of physical sex characteristics and thus all discussion of intersex variations.
Real biological essentialism is stating things like "men are XY and women are XX" and that example is interphobic because there are intersex variations that fall outside that.

Chevalier and Ehmke redefine it to cover discussion of any biological trait. In doing so they enable classifying intersex people discussing intersex variations as the same thing.
So any discussion of the genetic causes of an intersex variation (bear in mind that many of them are named for the nature of that genetic variation), is now reclassified as biological essentialism and thus transphobic.
