> The Old Testament is filled with violence but I don't think that reflects on Jews.

Of course it does, and I say this as a jew. Let's put it like this, being raised on a tradition whose first patriarch was ready to butcher his own son in order to prove his faithfulness to his imaginary friend, kinda paints father-son relations a certain way. Not to mention the whole circumcision thing, which is common to both jews and muslims.
