Katz and Frost are made for each other.
The piece that Katz links to by Frost demonstrates the deep hatred of feminists shared by Katz and the brocialists. Just as leading brocialist Hillary-hater Doug Henwood criticizes feminists much more harshly than he does the Koch brothers, Frost likes and admires Tucker Max and Neil Strauss far more than she does any feminists. Frost much prefers to harshly attack feminists, supported and encouraged by the brocialists at Jacobin and The Baffler. Frost previously defended misogynist men of the left - admiring men who are assholes and shitting on feminists is what Amber A'Lee Frost does. As a comparison - she's much less sympathetic to women talking about sexual assault in a public forum, calling it "industrialized confession" than she is towards industrial-grade assholes like Max and Strauss. No doubt Katz believes this indicates Frost would approve of him too, and he's probably right.
Speaking of the Koch brothers, Katz is a big admirer of their most prominent employee, Arthur C. Brooks.
All kinds of inter-connections among the feminist haters. But the main connection between Katz and Frost is that they both want women to defer to men. Katz explicitly tells women to be passive - in order that they may have relationships with traditionalist men (who are single in much greater quantities than more enlightened men, and so more likely to increase his match-up hit rate and further his career); while Frost, along with her contemptible brocialists-at-arms Liza Featherstone and Doug Henwoood want feminists to shut the fuck up about glass ceilings or careers or even the universality of rape(!) because the men have more important things to talk about.
Yes, dating hucksters and brocialists have much in common in their attitudes towards women.
