To answer one question above, I have read the web enhancement but not the book of which it is a web enhancement.
I was curious what the reaction would be if there had been a "Slayers guide to racial types" that then had a web enhancement including the prestige class "The Jew", with class abilities like "steal your money" and "member of cabal that runs the banks". I personally would object to that, and I have a problem with the prestige classes (the third might provide the closest parallel) in the web enhancement to "Slayer's Guide to Women" for about the same reasons. Is there a difference that I am missing? Or am I also too thin-skinned about "The Jew" prestige class idea?
