I can see where your argument is coming from -- there are, in fact, some stereotypical traits on the goblins, just as there are some stereotypical traits on most of the races in Azeroth. I am, however, saying that as a playable race, the goblins do not strike me as a Jewish stereotype so much as a combination of modern corporate entity gone horribly horribly wrong mixed liberally with entertainment-style depictions of the Mafia. Their traits also ping hard on the Mambo Italiano goodfellas and gun molls scale, particularly the women -- who do not particularly have "Valley Girl" stereotype speech patterns (that is, alas, the playable blood elf women -- really, my paladin does not come from California) so much as a rather broad New Yawk accent with accompanying Mafioso attitude.
