As for the Judaic holy books being violent, yes they are. Actually if you read the Pentateuch, or the Joshua you get nauseated of that much genocides and violence. However tell me how may Jews today follow those books going around killing people? Judaism for all intent and purposes is dead. It is nothing but a set of rituals and a feel good factor. The thinking Jews consider those stories as fables. So really Judaism does not threaten anyone. As long as the Jews do not represent any danger to anyone, then who cares what they believe.    

Muslims are killing people on daily basis. Muslims do not take the violent teachings of the Quran as old stories but as mandates from Allah for all times. Jews are not set to conquer the world, but Muslims are. Islam is not a personal religion. It is a plan to take over the world and establish the dominance of Allah.  

Yes both the Bible and the Quran are irrational, but there is a big difference. Judaism is no threat to anyone; Islam is a danger to human race.
