After she had her Nobel prize a journalist asked Tawkul Kerman that why would a woman like here wear Hijap because to him Hijap was a sign of cultural retardation and Kerman answered him saying that at first man kind didn't know clothes and during their evolution people started to make and wear clothes so what she wears is actually the top of human progressiveness.
Now let's answer this question from another side:-
Some Jewish women cover their heads and faces...in the west they call that dignity.
Some Christian women(nuns)cover their heads and faces...in the west they call that devotion.
Now since I believe I cleared my point I ask all the western people before you ask that kind of question to a Muslim ask him first:"do we_the west_have double standers toward you_Muslims and Arabs_about this thing" and if the answer is yes ask why and make an objective discussion with him and if he convince you try to read what we wrote about ourselves and was translated to your language and then believe me you'll find out that the west has double standers toward Arabs and Muslims in almost everything.
