I’ve read GG&S and it was fine. The more compelling arguments against it are too academic for me to understand, while the more superficial ideological arguments against it seem to boil down to this “You can’t just let white people off the hook!” myopia that totally misses the historical materialist argument being made.
I’ll spot you some amount of criticism on his historiography, but he’s not making any kind of argument that Christman didn’t make in his Hell on Earth arc, regarding the emergence of Capitalism. Or, for that matter, any Marxist has made regarding the origins and consequences of the industrial revolution.
