The distortion in Deirdre McCloskey’s angry letter to the editor [December 19] is of such large magnitude that it cannot be effectively corrected in a letters column. One example is that evidence for the theory of transsexualism she hates comes from my own research. It does not, at all.

Free access to my book and a detailed explanation of Ray Blanchard’s relevant research (and links to both supportive and highly critical writings by transsexual women) can be found at:
