The problem with the west is they do not want to even agree on the Quran and it's teaching. They think their books and Jesus Christ (PBUH) is the saviour and the son of God. Islam is peaceful if you are peacful and self defense is only what Islam teaches.
Lets see how many talk about the Crusaders I, II, III. Who killed the Jews? and who killed the christ? Not muslim but yes history can anytime be changed as it happened with Bible, Psalms and Gospel.
