My own adverse encounters with this stemmed from direct conflict with Chevalier in the middle of 2016 by way of the Geek Feminism wiki. In that case he used the policy documents he devised to silence my attempt to correct his definition of what #intersex is on that site (which states, amongst other things, that intersex is "under the trans umbrella").

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.
