The main thing I've learned from this whole affair is that the vast majority of the media is unwilling or unable to dispassionately read a relatively short document and address the content within it. James Danmore's (so called) "manifesto" never brought up women's limitations at all, he discussed the distributions of interested in the tech field between men and women and suggested alternative ways to make tech more attractive to women to increase the proportion of women in tech.

Maybe the research he cited was flawed, and maybe his proposals were unworkable, but there is nothing in that memo that should have been offensive to anyone who actually read it.
