I had a similar reaction to Scott’s take on “evil losers”. But the real measure of its effectiveness will be in whether and how widely it is taken up by others, particularly so-called moderate Muslims. Although Scott Adams knows a heck of a lot more about persuasion than I ever will, I suspect it will not be.
Calling people “losers” is something that is mostly done by other losers. I would probably have gone with something like “evil wackos”. That’s what they would likely be called in the West if they were driven by an interpretation of Christianity rather than Islam, and I think it captures the view of Muslims much better than “losers”.
