I absolutely agree it needs to be talked about, I just think it can be talked about in more constructive or nuanced ways than Mr Walker does. I'm sure he does get a lot of bile directed at him over stuff like this, which must be disheartening. But he seems to be buying into something of a self-constructed persecution complex which he now frequently uses to polarise discussion into US vs THEM. These days if you disagree with anything Mr Walker writes you're instantly dismissed as an idiot/misogynist/some sexy hybrid of the two, a perfect example was his response to the valid criticism of the limited dataset in his last "article" about gender imbalance in the industry. Actually a better example is the way he frames opposition in the text quoted in the OP, theres no room for reasoned dissent there, you either agree with Mr Walker or you are pushing your secret "keep my privilege" agenda. Because of course Mr Walker is never wrong? It's blatantly obvious that all Mr Walker is interested in doing is shouting at people, which may be required at the outset but doesnt actually lead anywhere. Also on a side note I feel it was a bit odd that the comments were turned off, I can certainly see the point in it, but again it just feels like an attempt to stifle discussion.
