Why do Jews and Arabs / Muslims hate each other?

Please forgive my ignorance here, however, I am currently reading John Gibson's "Hating America" and I find this issue rather interesting....sad and pathetic, but interesting.

Sunday school would have been much more interesting if we were taught about this....

"Question: “Why do Jews and Arabs / Muslims hate each other?"

Answer: The hostility between the Arabs and the Jews goes all the way back to Abraham. The Jews are descendants of Abraham’s son Isaac. The Arabs are descendants of Abraham’s son Ishmael. With Ishmael being the son of a slave woman (Genesis 16:1-16) and Isaac being the promised son who would inherit the promises to Abraham (Genesis 21:1-3), obviously there would be some animosity between the two sons. As a result of Ishmael mocking Isaac (Genesis 21:9), Sarah talked Abraham into sending Hagar and Ishmael away (Genesis 21:11-21). Likely this caused even more contempt in Ishmael’s heart towards Isaac. An angel even prophesied to Hagar that Ishmael would “live in hostility toward all his brothers” (Genesis 16:11-12)."
