Read the comments. Many of the commenters seem literally unable to distinguish between the concepts “Islam doesn’t discriminate against other religions” and “Islam is justified in discriminating against other religions”. And I mean “literally” literally. And these are the educated ones. I doubt your average Saudi would be able to comment on an English-language website.
I don’t know how to put this delicately: a lot of Muslims think very strangely. I tentatively attribute this to the lack (as far as I’m aware) of any history of debate or rhetoric, the practice of which has been valued in the Western world since Classical Greece.
