The sharia applies to all, not just to Muslims.
Islamic taqiyya gigolos and the media denies this but the sharia is applied to all as you can see here:
Bandeh Aceh, run by Muslim hardliners, does insist Muslim women cover their hair, but that law does not apply to Chinese women and foreigners, as the Jakarta Post points out:
Since 98 percent of Aceh residents are Muslim, most of the women you’ll see there cover their heads. But if you’re a traveling non-Muslim, Aceh Sharia Police will give you an exception, as long as you’re a foreigner and able to show your identity as proof that you’re a non-Muslim.
So why this submission by the ABC?
For a contrast in courage, take the late and great Oriana Fallaci, interviewing the Ayatolla Khomeini in Iran in 1979:
FALLACI: That’s not true, Imam. In any case, I am not only talking about piece of clothing, but what it represents. That is, the condition of segregation into which women have been cast once again, after the revolution. The fact that they can’t study at university with men, or work with men, for example, or go to the beach or to a swimming pool with men. They have to take a dip apart, in their chadors. By the way, how do you swim in a chador?
KHOMEINI: This is none of your business. Our customs are none of your business. If you do not like Islamic dress you are not obliged to wear it. Because Islamic dress is for good and proper young women.
FALLACI: That’s very kind of you, Imam. And since you said so, I’m going to take off this stupid, medieval rag right now. There. Done.
