So I am confused now: which cartoons are permissable and which are not?

"‘This cartoon is discriminatory,’ the prosecuting authority said of the sketch on the website of the Arab European League (AEL) which it said depicted the Nazi holocaust as a figment of Jewish imagination. ‘This is offensive to Jews as a group,’ said a statement. Last month, Dutch prosecutors ordered the league to remove the cartoon from its website or face prosecution." (thanks Adeel)
