I've written and rewritten my response to this piece about 5 times now... I've even quoted Bob Dylan's My Back Pages, and I still feel that there's something relevant there.
My considered opinion is that there's nothing to be gained here. I genuinely cannot understand the complete and utter condemnation of Damore's original transgression. Those who can understand why it's such an egregious piece or writing are so certain of their rightness that they are unable to countenance the need to explain their position.
Apart from the undoubted sincerity of Kieren on this matter, I take away nothing to help me grasp why he says what he says.
