You said it soooo well, when you wrote: "The faults of ancestors cannot fall to their descedants."
So, why 7,500 Jews killed in Italy?
Romans were dirt and even the history of modern Italy is also not good. That is the first country, which produced fascists.
Why the Jews were killed in Italy was not a secret, but the difference between me and you is that I didn't and don't support the fascist regime, and I have no problem to admit that what happened to them in Italy and in Europe was something to be ashamed of, that doesn't have to be repeated again.
While you are not enough man to condemn the evil actions of your loved prophet, but hypocritically you want to take the defense of Jews when they were killed by Europeans.
