I dunno what great points you're referring to, his "theory" is pretty much incoherent garbage the last time I checked (mixed with clumsy restatements of actual theory).
Agreed, I've been told how amazing his theory was by Maoists and I read it and just think...really? This stuff? It's either just regurgitations of things others have said, or whacked out bullshit like "War and adventurism are good things actually."
