Finally, you failed to put forth a single refutation of how the immigrant of today is similar to that of 1906. You can't because they are different.
I definately agree with you that the vast majority of Italian immigrants were not part of the mafia, but it seems you are more than willing to engage in the same type of rhetoric that smeared your family and heritage for decades.
The objective facts are not in dispute. I agree that immigrants of yesterday were tarred with similar labels, etc etc.
However, the fact remains that Italian immigrants did not demand that the society assimilate to them, they assimilated to it because they loved this country, as did most other groups at that time. Today, I believe, you have a different dynamic at place. Many of these wonderful workers want to exploit our system, not abide by it. They have willing accomplices in employers who want to avoid taxes that the rest of employers must pay.
