Everybody's in a rage - the men, the women, the girls and boys - somethings got to be done to save these people from their "religion."
Their book has a saying that goes something like "the death of the self is the path to salvation," but they take it literally to mean the death of the physical body, rather than the death of the "ego," or false self.
Slay the infidel wherever you find him is taken to mean people who don't believe as they believe, rather than the 'devils' within - what Christians would call "bad thoughts" or egoism, etc.
If only they could wake up and realize they're doing the exact opposite of what their book actually says - realize it's an inner struggle, not an external one - then they, and everyone else on the planet, would be better off.
Not to mention the sigh of relief we can all have then.
IMO
You err on this point: Sura 9:5, in context, is about conducting warfare against unbelieving pagans. Muslim historians are in basic agreement that the context of this passage pertains to a pilgrimage that took place about a year after the conquest of Mecca. According to this "revelation," during the sacred months of the pilgrimage, any treaties with the pagans were to be honoured; after that, they could be warred upon.
In other words, in Sura 9, "slay the infidel" most certainly means, go out and kill non-Muslims.
