99 percent of Indonesia, which is an Asian country, is Muslim. Many Muslims elsewhere, too, are Asian. It's a religion just like Christianity or Buddhism. The man obviously could tell these women were Muslim because they were wearing the suppressive head covers. They could have had pale skin and blue eyes for all we know, but it's the head covers (and sometimes the body clothes) that give it away. Oddly, some Muslim women wear only the head scarves but very Western clothes, while others are attired from head to toe in suppressive wraps. It's sad how they are taught to shield what could be very beautiful hair from the public. I recently saw a man and his Muslim wife and preschool daughter. The child of course did not have the head cover. She had gorgeous ringlet gold-colored hair. How sad that beginning at about 13 or 14 she will "have to" cover it when she goes out.
