No, postmodernism and feminism are rooted in Marxist ideology. Marxist intellectuals shifted to postmodernism in the 1970s after it became impossible to deny that Marxist doctrine had led to authoritarian police states and democides all over the world. Postmodern ideology changes Marxism's fixation on capital with a fixation on power, and replaces income-class with race/gender/income-class identity groups. It's extremely similar to Marxism in its perspective, goals and methods.
The evolution of postmodern ideology is well-documented and so his claim can be validated. Even the reaction to the memo validates the memo author's claims, as it shows the dogmatic, sexist/racist and hateful nature of postmodern/feminist ideology.
With respect to the ideological foundation of postmodern/feminist ideology: the fact that one fifth of social scientists in today's universities identify as adherents of Marxism - an ideology as murderous as Nazism - is a testament to its prevalence in academia, and the malevolent nihilism animating postmodern/feminist ideology.
