You see now this is why you Euros have so many problems with Muslims, you think you are progressive but do stupid shit like this. My sisters do not like or wear the veil and I have always stood by them in this even when my father was initially reluctant to agree but I have a cousin who wears the veil because she wants to and trust me if someone grabbed her veil the way you are describing they would eat cement not soon after. Now if it was a teacher that would be an entirely different matter because the idiot would both be out of a job and looking at a lawsuit.
In the US we have the same no hats in school rule but religious head wear does not apply, so Muslim girls and even Sikh dudes wearing Turbans are not told anything. Maybe that is why American Muslims are not bat shit angry like Europeans Muslims.
As for your girl not wearing a head dress while inside a mosque most Imams will let such things slide for tourists but quite frankly you might have thought this as progressive but it would be considered disrespectful in most mosques. One time in my mosque a female police officer came inside with a few firefighters to check if the signs for regulations were put up and she stopped at the entrance and asked the Imam if her entering without head wear would be disrespectful and if so she would stay outside, he just smiled and told her that her asking shows that she meant no disrespect and she is welcome to enter as is. That is American progressiveness versus European progressiveness.
Markus is a retard and his comments have little to do with the video which @
