This is beside that there are over 100 verses in the Quran instructing its followers to fight and kill ALL non believers. It is your opinion that you deem them to be "inflammatory".
How many in the Old Testament? How many such exhortations in the papal bulls published between 700 and 16000 AD (which would be roughly contemporary with the Muslim empires)?
It doesn't matter. What the aggressively militant branch of any religion considers crucial [sic] to their cause at any given moment of political upheaval in the world doesn't inform every aspect of that religion as practiced by the majority of its adherents.
Every religionist, of every shade, has to pick and choose their workaday beliefs and their holy-day actions, because the ancient books are full of contradiction, mistranslation and traditional interpretation, and none are 100% applicable to modern life -
not even if that modern life is theoretically based on the 18th century model of simplicity. No people can stop time and change. All they can do is adapt, and the adaptations vary according to time, place and circumstance.
Islam began as an outgrowth of the Judeo-Christian religious continuum, and was originally meant to coexist peaceably with its precursors. But the next generation leaders would have none of that: they embarked on a campaign of territorial conquest and took major Christian centers in the mid-east very quickly (with some justification: the Romans occupied Arab lands) - nor would the militant Christians. Their mutual hostility became entrenched quite early on. (Nobody asked the Jews, they were long dispersed by then. But eventually came back - just as intolerant and unforgiving as the other two.) None of this was really about religion; it was the usual geopolitical dance: who controls more territory, more population, more cities and trade routes, more wealth. Religion is just a handy recruiting tool: spiritual zeal is a great motivator of young men to rush to their doom. Hence the crusades and all the other sordid messes.
Why atheists don't attack Islam as much as they do Christianity: it's because of demographics. Most atheists on these forums grew up under the heel of one Christian denomination or another. When Muslims are disenchanted with their religion, they're just as vocal. Just, they're not as well represented here.
