Why does political correctness fall away when it comes to the niqab? Because other Islamist inroads, like Sharia banking, happen offstage, so to speak. They are not “seen” by the public. But the niqab is open to the collective public gaze. Individuals responding to their own discomfort observe that discomfort mirrored in other people’s faces, which in turn emboldens them to protest. Politicians know grassroots support when they see it and several Western leaders have seized the moment for legislating partial or full niqab bans.
If governments and the media would educate the people that these garments are the same as KKK or Nazi uniforms, we'd get rid of them faster.
