OK there's a few things to unpack here. Firstly, if someone's criticising a book that you've recommended for making incorrect generalisations, saying 'it seems OK to me' isn't a brilliant defense. With that in mind I'll go through my first post and add some substance.
Step 1: Make some generalisations and misrepresentations about a diverse group of theorists. Here's a quote about postmodernism from the book.
“[A] new religion, a tradition of faith that is actively hostile to reason, falsification, disconfirmation, and disagreement of any kind.” Which of course ignores the fact that postmodernism is not hostile to reason, and that most postmodernist thinkers spent a lot of time disagreeing with each other, and responding to criticism of their work by non-postmodern thinkers.
Then there's the fact that they boil the entirety of Foucault's thought down into 2 points: radical skepticism about whether objective knowledge is possible and a belief that structures in society decide what is true. That's not what Foucault says. Firstly, he wasn't interested in finding out what was true, but rather in what we think is true causes us to act like, so they've got it backwards. And secondly Foucault wrote about power being relational and not zero-sum. So again they've got him backwards (perhaps deliberately in an attempt to link him to contemporary scholars).
So they've inappropriately lumped together a bunch of distinct theorists with different views and the main intellectual thrust of the book is based on a misreading of Foucault. I wouldn't call either of those things "perfectly reasonable" but you've already mentioned how the book spoke to your lived experience so perhaps you looked at these missteps with a less critical eye than I did.
Step 2: Make a tortured link from those generalisations to contemporary social justice movements. The book traces postmodernism through an 'applied postmodernism' phase and then into contemporary 'reified postmodernism'. The problem is that most of the contemporary thinkers are not postmodernists at all. In fact, some of them sit within the liberal tradition that the authors claim to be defending. Then there's the fact that quite a lot of the theorists that they claim to be quoting are actually misquoted, quoted out of context, or quoted to mean a completely different thing to what they're actually saying. So the authors are making up quotes and attributing them to people that never said them, in order to justify the link between (their misreading of) Foucault and (their caricature of) modern theorists.
As an aside, I'm not sure that there's much of a link between activists and social theorists. Postmodernism is primarily a tool of literary analysis, not a way of mobilising people onto the streets in protest movements.
Step 3: Become a darling of the right-wing media. This is just a description of what happened to Lindsay after the book was published. While theorists either vehemently disagreed with it, ignored it, or mocked it, right-wing media outlets gave it gushing coverage.
OK, now let's talk about me "spiralling off into an ad hominem attack of little substance".
Step 4: Partner with a Christian nationalist to set up a fake liberal website and spend most of your time laundering right-wing talking points (A cabal of Jews was trying to bring down Western civilisation from the inside and that's why the far-right can recruit more anti-semites; queer theory is in bed with radical Islamism; climate justice is communism; etc). Is it an ad hominem attack to point out who is funding someone's research? Because New Discourses, the website that Lindsay writes for, is funded by Michael O'Fallon, who also runs a website called Sovereign Nations which aims (I'm not going to link to it) to be "a prolegomenon to the formation of a new, and not just sentimental, conservative and Constitutional Republic" and is heavily involved in right-wing religious nationalism. O'Fallon and Lindsay have also shared numerous other platforms where they promote absurd theories together. So, to reiterate, is it ad hominem for me to point out that this team of so-called liberal rationalists are either partnered with or employed by (possibly both) the religious right? Is it ad hominem to say that they're laundering right-wing talking points when that is what they're actually doing? Or is it an honest description of their activities?
So what about the substance? Well on a previous page of this thread somebody linked to some of Lindsay's tweets, where he says that woke Jews cause anti-semitism (
link) and that "the Frankfurt School really did want to end Western Civilization and is almost wholly comprised of Jews. This allows anti-Semites to recruit new anti-Semites
who wouldn't have otherwise been recruited" (
link). So victim-blaming and some classic cultural Marxism conspiracy stuff. In other words, laundering far-right nonsense.
In the same twitter thread he states that "another Critical Theory, Queer Theory, partners with radical Islamists (not famous for their tolerance of gays) against Israel" (
link). And I'm not going to link to it but if you search for 'Michael O'Fallon James Lindsay climate' it'll bring up a youtube video where they make the link between climate justice and communism.
That book isn't really serious scholarship, but then it's not supposed to be. There's two arms to this point. The first is that this book isn't serious scholarship. It's not. Between the massive simplification of decades of theory written by people with many differing viewpoints, the misreading of Foucault, and the misquoting of modern scholars, I don't think it's a stretch to say that the scholarship isn't serious. There are also technical issues with the scholarship, including incorrectly citing works, which don't fill me with confidence about the depth of their critical engagement with the material.
As for the what the work actually is, if it's not serious scholarship, that's a bit more of a reach. However, to me there are two reasons for supposing that this is a work of culture war positioning rather than serious scholarship. The first reason is Lindsay's connections to reactionary right-wing figures such as Michael O'Fallon and
Christopher Rufo.
The second reason is that the very accusations that the authors level (wrongly) at reified postmodernism can be leveled at their work. For example, they claim that postmodernism is “[A] new religion, a tradition of faith that is actively hostile to reason, falsification, disconfirmation, and disagreement of any kind” while only 1 of the theorists that they cite even comes close to making that claim. According to their view, reified postmodernists accept no disagreement, because your disagreement with them is representative of your power and your power means that your disagreement is invalid. I think Robin DiAngelo would probably agree with that statement, but none of the other cited theorists would.
But what happens if you disagree with Lindsay et al.? Then you become part of the evil woke that's trying to silence them. Which appears to me to be exactly the argument that they reject when it comes from reified postmodernists. As such, to me the book reads more as a sketch of right-wing victimhood and projection and a new frontier in the culture wars than a serious piece of scholarship.
I'm always suspicious of so-called 'genuine questions' but the source for that statement is
here. "[T]he Frankfurt School really did want to end Western Civilization and is almost wholly comprised of Jews. This allows anti-Semites to recruit new anti-Semites
who wouldn't have otherwise been recruited". It's been briefly discussed on a previous page of this thread too.
