I have no idea. I'll take your word for it. But I did specify in post #50 that I was unconcerned about women voluntarily wearing a hijab -- not their being forced to by Salafi fanatics.
The hijab is entirely different from the niqab or burqa because the face is uncovered, so there isn't the problem of identification, and it does not by itself offer the tent-like body covering which is a security problem for smuggling things (or for hiding male jihadists).
I was essentially saying that wearing the hijab was a political statement. Wearing a niqab is a security risk, though there were a few older Muslim communities (I’m thinking odf Atlantic Avenue in Brooklyn Ny)where you would occasionally see a few women wearing it. it was definately not common.
