If Muslim Syria can ban full face veils because they're not required by the religion . . .

why can't any Western nation?

Syria has forbidden the country's students and teachers from wearing the niqab — the full Islamic veil that reveals only a woman's eyes — taking aim at a garment many see as political. . . . The veil is linked to Salafism, a movement that models itself on early Islam with a doctrine that is similar to Saudi Arabia's. In the broad spectrum of Islamic thought, Salafism is on the extreme conservative end.

Muslim Syria now joins Muslim Turkey, Muslim Egypt, Muslim Jordan and Muslim Lebanon in recognizing that the full veil is not a "religious obligation" but "a declaration of extremism" endorsed by the most radically fundamentalist branch of the world wide Muslim community.

Why would any one in the West disagree?
