The fashion show was "Christian" in the sense that it was held in a Christian village. Hamas would make sure that Christians would abide by Islamic Sharia norms. "Wherever there are Christians there's moral decline."
Sharia Alert: "Christian fashion show angers Muslims," from the Irish Sun, June 28 (thanks to Twostellas):
A fashion show held in the Christian village of Beit Sahour, near Bethlehem, has been condemned by Muslims in the area.
The fashion parade, which was permitted by the Palestinian Authority has drawn strong opinions from Hamas and other Palestinian factions.
Top Hamas political figures in the West Bank, have condemned the show as immoral and said it never should have happened in an area under Israeli occupation.
Saying the parade had violated Islamic values and laws, local Hamas officials said that such events were considered by Islam to be a fahisha, or major sin.
President Mahmoud Abbas and Prime Minister Salam Fayyad were strongly criticised "for supporting the fashion show, and spreading moral corruption in the West Bank."...
Palestinian Web sites were flooded with postings following reports of the parade, with writers denouncing the show with comments such as "Wherever there are Christians there's moral decline" and "Were it not for the presence of Muslims in Palestine, Palestine would have become like Paris. One big brothel."
