Mark recommended Cynical Theories by Helen Pluckrose and James Lindsay in replies under this post.
Extract from the description on Amazon:
Helen Pluckrose and James Lindsay document the evolution of the dogma behind these ideas, from its origins in French postmodernism to its refinement within activist academic fields. Today this dogma is recognisable as much by its effects, such as cancel culture and social-media pile-ons, as by its assertions, which are all too often taken as read in mainstream media: knowledge is a social construct; science and reason are tools of oppression; all human interactions are sites of oppressive power play; and language is dangerous. As they warn, the unchecked proliferation of these beliefs present a threat not only to liberal democracy but also to the fruits of the Enlightenment itself.
This sounds like a must-read!
