First you say, “(1) Despite speaking very authoritatively, the author does not appear to understand gender”.
And then quickly proceed with, “I’m not going to spend any length of time on (1); if anyone wishes to provide details as to how nearly every statement about gender in that entire document is actively incorrect,¹ and flies directly in the face of all research done in the field for decades, they should go for it. But I am neither a biologist, a psychologist, nor a sociologist, so I’ll leave that to someone else”.
You are the one responding to the manifesto — the “providing details” part is on you. Otherwise, what’s the real purpose of your response? Lost me right there, Yonatan.
And you seem to have a funny understanding of either speaking authoritatively, or irony.
