The problem with “diversity” is when it is used to crush dissent. It must be acknowledged that worldview differences are as legitmate as skin color or gender differences. And it is this oppression that breeds anger and hostility, with that anger being directed at those that different, instead of being directed to those that are corrupting the concept of diversity for political and economical gains. His rant against females in IT is an example of that anger. The problem is not the females but bosses trying to dictate what the employees can think and feel. Modern corporations demand feudal obedience (“I will to my lord be true and faithful and love all which he loves and shun all which he shuns…”) while giving late-capitalism job security.
His rant is just a bad reaction to a big problem in modern corporations.
