Poor Muslims! I’ll bet they can hardly leave the house without getting offended by something here in the land of the dirty-dog infidel. I am not too easily-offended, but in some ways I know how they feel; for example, whenever I drive past a mosque. Or, when I see women in burkhas safely enjoying a shopping mall in my country, and I think about how their co-religionists are slaughtering my co-religionists in Muslim countries.
When I see a muz in public, I make the Sign of the Cross.
The initial forehead tap is done slowly. He/she/it wrongly assumes I am making a salami gesture. The look of surprise/distain/horror is priceless.
