There aren't really any. Italy is a very xenophobic country, not on the level of Japan, but similar to Eastern Eu. They don't appreciate other cultures, other values than their own, any infringing religion or other ethnicity. Coming to think of it, had it not been such a poor country, most getbiggers would have enjoyed the place. Though, they are derogatory against everyone so Americanos are not viewed in any favourful manner.
to tell you the truth mate, Italy is not xenophobic at all, not even in the south and poor areas.
don't want to sound in search for politically correctness, just telling you as it is.
i live here and this is reality.
we also have lots of Hebrews and as everywhere you have the good and the bad.
nothing new.
