Ignorance, you say?

"Prophet, make war on the unbelievers and the hypocrites and deal rigorously with them. Hell shall be their home: an evil fate." (Sura 9:73)

"Those who reject Faith fight in the cause of Evil. So fight ye against the friends of Satan." (Sura 4:76)

"Fight and slay the Pagans wherever ye find them, and seize them, beleaguer them, and lie in wait for them in every stratagem of war." (Sura 9:5)

Islam is a genocidal ideology, no better than Nazism, and equally at war with Western civilization.
