Full points for yet another vigorous take down of the google manifesto strawman. 

Nowhere did the manifesto equate coding with "simply mechanical... mathematics or logic" nor did it "take the extreme position that genetics neatly determines behaviour."  It argued against workplace initiatives aimed at increasing the number of women, which the author felt were discriminatory, and it provided support for the position that having an unequal amount of men and women in a certain job might not be a bad thing.  

I sincerely find it hard to believe that writers of editorials like this actually ascribe to their own logic.  More likely, they have decided that it's acceptable to mislead the masses in pursuing an idealist vision of society that will somehow be better for all.  I'm sure the author is being rewarded with approval from his peers.
