Actually Sir J Islam does NOT consider Christianity or Islam legitimate religions quite the opposite. The Koran and unfortunately to this day mainstream Islam beliefs define ALL non Muslims as illegitimate in fact. Now in regards to how many they have slaughtered in histort let's just say their extremists and fundamentalists have not discriminated against Hindus, Siekhs, Bhuddists, Zoroastrians Jews, Christians, Yazidi, Berber, Kurd, Bahaiis, on and on. They are equal opportunity when it comes to religious wars including sects of their own religion particularly the Amidyah.
That said sometimes some tongue and cheek is needed. Think about it. I say this as a Jew as well. I respect all religions but for phack's sake, taking religions literally is b.s. whoever does it. My religion did not teach me that I could not share land and live with Muslims. I can't if they want to wipe me out and do not define me as an equal. Its that simple.
More to the point Jerusalem is a matter between Israelis and Palestinians no one else.
Next I don't like anyone with a beard. They are up to no good. Castro, Marx, Jesus, Moses, Muhammed, Marvin Gaye, that NDP leader, Prince Harry, all trouble.
