Why, what's so offensive in the Don Vitone nickname to make him mad? Vito Cascio Ferro was called Don Vitazzu, many bosses named Giuseppe are called Don Peppino etc, it's not like Antonino "Ferocious dwarf" Imerti or Toto' "the short one" (u curtu) Riina (also known as "the beast").

Vito Genovese was suspicious of all non-Italians and resented having to work with Jews such as Meyer Lansky and Benjamin ‘Bugsy’ Siegel early in his career. Vito once complained to Frank Costello, in front of Siegel and Lansky, ‘What are you tryin’ to do? Load us with a bunch of Heebs?’. Before Bugsy could flash his trademark temper Costello stepped in; ‘Take it easy, Don Vitone, you’re nothing but a God damn foreigner yourself’ and Genovese kept quiet.
