You know, there are times when I have to wonder if this is a war between the corrupt Jewish mafia and the corrupt Italian mafia. It seems to me that being Jewish or Italian is the problem, its the behavior that is the problem. Act like a criminal, then you are a criminal, regardless of what ethnicity you may happen to be. Goes for EVERYONE. It's BEHAVIOR that is the problem, not your particular ethnicity, although that can be a factor sometimes.
Ancient bloodline feuds do exist, but I believe the main one is between Jacob and Esau. It is STILL being played out today.
