Orthodox Jewish men can’t shake women’s hands either. So I don’t have a problem with this as stands. However, why are these guys getting citizenship? I’m wondering if they found some lonely Swiss women who married them?
Well, I'm a Christian male who taught math for a number of years at a Lubavitcher Yeshiva (it's a long story).
Anyway, there were many women teachers there, and many women held positions of authority. And when the Yeshiva's religious restrictions were pointed out outsiders like me, it was always done gently, and with respect.
I doubt if any of that would occur at, say, a mosque.
Aside to Yaelle: I know you're not equating Orthodox Jews at all with Islamists.
