I think intolerant religion must not be tolerated in an open society. I think that a society has absolutely no obligation to try to be amenable and welcoming to any ideology. When I travel in a Muslim country, I don't go around at noon during Ramadan eating ham sandwiches and drinking beer. That student is doing exactly that. She's literally spitting in the face of the country that hosts and educates her.
Yes, the professor may have tried to teach her students about the complexity of the world. That's the very definition of her job, after all!
The next step for a person like this student ends in a Samuel Paty or Charlie Hebdo. My advice is to deport her back to her miserable, war-torn, fascistic backward country she shouldn't have left.
Tolerance is great, but must be with at least a modicum of reciprocation. As Paul Claudel said "Tolerance? There are houses for that."
