Its really a shame. When you say the word "Italian" I think Marcello Mastroanni. To many out there, however, it means guys from Staten Island in shell suits who DON'T EVEN SPEAK ITALIAN and can't pronounce calamari correctly! Hey Guido, here's a hint, it aint pronounced "calamad." ;-)
When I was growing up, the names with vowels I knew were about taking care of each other. Family was sacred. The family with vowels were about helping those that came over on the boat. It was a network that watched your back.
Even if there was a business matter that needed taken care of, it was done with respect.
I've no idea when all this drug stuff and gambling crept into the vowel stereotypes. I've no idea when the original vowel people went bad.
