Obviously, it's best to not play their semantic game, as it accepts their framing.

However, if you have to play, poison the well by insisting on "biotypical" rather than "cis" as a frame. "Biotypical" should be our "preferred" self-label because it's got the same pseudoscience feel to it, just like "neruotypical" (an 'in' phrase to describe "normal" by mentally ill wokists) and is a subtle dig at transgenderism flying in the face of biology.
