Me: These authors are clearly anti-semitic
Hermann: Why? Are they advocating racial or religious hatred of Jews? It certainly doesn't appear so.
What convinced me was this line "The Lobby" (their capitalization), an overwhelmingly Jewish force abetted by some Christian evangelicals and a gentile neocon collaborator or two, who have hijacked American foreign policy and controlled it for decades."
That is a statement of a perceived fact. It may or may not be true, but there is certainly nothing hateful in the statement that implies an irrational dislike of Jews by the authors.
Cries of anti-semitism about this paper simply reinforce the common view that what is really "anti-semitic" is anything that Jews and their friends don't like or disagree with.
