Two remarks:

1. While I do not agree with this man's "manifesto", in an inclusive workplace he should be permitted to express opinions and be of a culture that differs from mine. The fact that, for example, I find some religions ludicrous, does not mean that those who believe them should be fired.

2. It would be well worth some journalist comparing the situation at Google (male dominated workplace) with the game of chess. In that game girls participate and are equal in ability to males until about puberty.  Then the majority leave the game.  Clubs want females to play and actively encourage them.  Women are fully capable of extremely strong play.  They choose not to play. Not because they are driven out, not because they lack physical strength, just because they choose to leave.  A parallel?
