The Blogosphere(tm) is correctly going starkers about this poster. I'll quote from the target site:
This poster, funded by the Associated Students of San Francisco State University, was posted on campus in April2002. This is perhaps the most grotesque and explicit incarnation of the "blood libel" observed in the free world since the Nazi Holocaust. It was generated on the campus of a public university by students, using public money. The poster included the names of the following organizations: Associated Students, GUPS (General Union of Palestinian Students), MSA (Muslim Student Association) and WIA (unidentified).res ipsa loquitur...Latin for "the thing speaks for itself".
