Ummm, yes you do. You don't recall the movie "Bugsy" that came out a few years ago? Plenty of films have been made about Lansky, Seigel and other Jewish mobsters. Still more if you watch the History Channel or the Discovery Channel.
They didn't have the impact that the "Godfather" movies have had (and their multiple offsprings) so the Italians get more ink about mob ties than the Jews do but the Jews have had their share (There was Hyman Roth in the Godfather movies too).
I'm neither so it's not my issue. If you really wanted to fight stereotyping, you might take umbrage at the fact that most of the Jewish mobsters were portrayed as shrewd businessmen.
-------------------
The figure of Roth in the movie was very loosely based on the figure of Lansy. Lansky, of course was never killed. He was in association with Vinie Alo, the Chicago heads of the mob, and, and the labor unions. As alluded to in the movie, this coalition was going to set up a new Las Vegas in Cuba after which they would all go legit, which is what they wanted to be all along. Castro put the quietus on it.
