This book was referenced in another book I'd recently read, and it seemed intriguing: written in 1995 amidst the "science wars", the "PC wars", and so forth, how would the "culture wars" of that time relate to the political strife now (fall 2016)?

Very much so. Very, very much so. There are passages, almost entire paragraphs, that you could lift from the book and you wouldn't be able to tell (minus one or two references) if they had been written then or now, particularly re: white (and, particularly, white male) anger, frustration, and resentment (regardless of how you view that) and the political capitalization of that by conservative political power. (To the point that Trump is now making the Republican party the de facto white identify party.)

Overall, the book is a criticism and call away from identity politics, and a call toward the (re)establishment of a common Left. I'm not sure if that is a project who's time has come, though I don't see what other (even passably good) options exist. ( )
