Thanks for responding, Mark, and apologies for my tone. One of those responses written in haste and provoking editing remorse at leisure.
I'll go back through your earlier work. I'm trying to get up a proposal to do some research in the space from my own position as an anthropologist interested in culture-neurology relationships, especially around dimensions of sex biology (and gender role) often considered innate. I suppose I'm on a hair trigger around the issue of multiple masculinities. A reminder to me not to project when someone has written what is clearly meant to be a very precise intervention: the cheapest critique is always pointing out what an author never set out to do in a particular piece and saying that part is missing... My error.
