I do not understand the point of this post. It seems like the real target is multiculturalism, and it's general defense of Islam. Because if it were simply directed at Islamism, it seems like an awful lot of bother over an ideology so obviously absurd to modern Western sensibilities. You'll have no argument from your peers as to the legitimacy of anything this fellow espouses, except for on the grounds of "tolerance".

So in the absence of anyone with whom to quarrel, you may as well begin bemoaning other, equally pathetic, social phenomenon, such as serial killers, rapists, pedophiles, etc. But what would be the point, right?

And so I suspect the actual target of your righteous indignation is not the Islamist himself, but the liberal social response. And that would at least make for a sensible discussion. On its face however, it merely seems like a masturbatory rant.
