Why do Christians look respect Jews and look down upon Muslims?

Is the fact that people generally look upon the Jews as true worshipers of God and followers of a legitimate faith extraordinary, even if they consider them misguided by not following Jesus (pbuh) but killing him? On the other hand, Muslims are looked down upon as followers of a false prophet and savage blood thirsty terrorists or barbarians. Muslims have given Jesus and Mary (pbubot) their well deserved respect in many places of the Quran. Noble Quran 3:45 is one place where this happens, but according to the Jews that people look up to, Jesus (pbuh) is a phony, fraud, fake, that man, a sorcerer, trickster, deceiver and other bad stuff. They even say all kinds of stuff about Mary's (pbuh) chastity. For the Jewish Talmud legends about Jesus (pbuh), look up Dr. Josh McDowell.
