Typical. Defending anti-Semitism is OK sometimes. 
My favorite comment comes from a "writer/contributor at VDare." That's right, a writer for a white nationalist publication thinks some anti-Semitism is OK!
I find it interesting how many so-called liberals/progressives can peddle in centuries old stereotypes as if it ain't no big thing. Waters comments about the "Jewish Lobby", especially in the record business, sealed the deal on him. Of course, like most bigots (also in those comments on the link you provided) when they start regurgitating anti-Semitic (hell, any bigoted stereotypes), they never forget they "have Jewish friends" or are "related to a Jew," as if this magically means what they are saying isn't anti-Semitic. 
It is also interesting how many 'don't care,' or blame Jews themselves for anti-Semitism.
I apologize for the time; I said I would answer, but the holidays were lazy days for me, mostly spent with my sweetie-honeys and four hyper chihuahuas (the weather was so bad they had to stay inside). Anywho....
Outside of sexism, anti-Semitism is one of the most pernicious and lasting hatreds that plagues the world. Some of the modern day hate is focused on Israel, but much of it is still directed squarely at us, as a people. It knows no educational limits, no social barriers, no ethic boundaries, it will infect anyone, even other Jews. I saw you noticed another thread about a new movement, the quenelle, a discreet way to do the Nazi salute. Of course, many scoff at the notion of the "new" anti-Semitism, which is almost always directed at Israel, thus the addition of the word "new." It isn't actually new or even inventive, it is simply the same anti-Semitism with the word "Jew" removed and the words "Zionist" (or another of its forms) or "Israel." Which leads me to your next question...
I didn't read "World War Z", but I did see the movie. My brother read it and said the book was infinitely better. Those that read the book, said the portrayal of Israel was "to excuse Israeli "Apartheid", Zionism, and to show that Jews were smarter than anyone else, but it can be expected because it was written by a Jew" (Mel Brooks' son). The movie version was excused as "showing it differently from the book is to make people sympathetic to the Jew." That was from the talkbacks at Yahoo! (as I remember it or a similar site), and I found similar comments at the National Vanguard and a source that has been used here (I just can't remember if it was the Veteran's website or VDare).
There are some really interesting anti-Semitic sites out there and can be educational to read, though it should be done on an empty stomach.
