The authors of this book do not claim that these statements are true, although I think we would all agree that they are all partially true.
The point is that for 200 years the opponents of western civilization have believed them to be true. It isn't really relevant to me whether your beliefs are accurate if you believe them so strongly that you are willing to kill me for them. The relevant factor is the fervency of belief, not its degree of truth.
It is also highly relevant that these exact same criticisms of western civilization are behind the core anger and hatred for it seen among liberals/leftists. Socialism, environmentalism, racism and other "issues" of western civilization are not and never have been the real problem for leftists. The real problem is that they hate our society. The issues are merely a convenient club, which is why when one is discredited (as with Communism) they merely drop that club and pick up another without breaking stride.
IOW, they don't hate America because it isn't socialist, they promote socialism (environmentalism, animal rights, feminism, etc.) because they hate America.
