Here’s an interesting test case. According to this story, Youssif Z. Omar, a native of Libya, physically dragged his 14 year old niece from a Columbia, Missouri high school on the grounds that she was not wearing a hijab.
My take: that is not our custom. Men do not drag little girls around by their hair for any reeason least of all for not wearing a veil. If the facts are as reported and he is not a U. S. citizen, his visa should be cancelled (regardless of its nature) and that should be handled administratively to the greatest degree possible. I’m afraid that would run into 14th Amendment issues but it’s my opinion.
He’s clearly a guy who doesn’t care to comport himself according to the rules of his host country. I’m against banning the wearing of hijabs but I can see the argument for doing so which involves guys like this.
