I think it's adorable that you actually believe she has a choice.
But hey just think, at least you're as progressive as those wonderful groups like the Taliban, al Qaeda, ISIS and the countries they're ruining, as well as those great bastions of freedom and democracy like Saudi Arabia and Iran.
The Taliban did not allow women to wear the niqab. It required them to wear the burqa. In that sense, you're just like them by telling women how to dress and not dress.
Irán requires women to wear loose-fitting non-revealing clothing and to cover their hair. It also does not require them to cover their faces though it does allow them to do so sinse it is a common practice to wear the niqab in Iran's south. Whether it prohibits face covering in some cases, I don't know but I doubt it beyond what might be required for legitimate reasons. The only place it might require the chador (which also does not cover the face) is at the mosque, and there chadors are lent out to those who don't have one.
Again, you're just like Irán trying to tell women how to dress and not dress except that Irán is one step ahead of you in at least going them the choice to cover or not cover their faces. In that sense, you're more like the Taliban in opposing that choice.
I'm not familiar with ISIS' and Saudi Arabia's policies on the matter, but maybe you could enlighten me on them.
By the way, I'd seen women wear the niqab in Urumqi. Guess where that is.
The saddest part is that while even Irán gives women the freedom to choose whether or not to cover their faces, Canada, just like the Taliban, wants to take that freedom away. And to think that even Irán thought the Taliban to be extremist!
The only four other governments besides the Taliban that I know of which have taken it away are officially atheist states like China (and even it allows the burqa in unofficial contexts) and closed secular extremist states like Turkey and France and Quebec which have either also banned crucifixes or at least tried to.
