It is objectively wrong for anyone's beliefs to dictate how others should live.
If women want to cover their face for their own reasons, that is fine. I would still be concerned that such an attitude would be born out of false consciousness and accepting a misogynistic culture, but even if my concerns are valid, there is only so much that it is just for me to do. People must change and grow at their own rate.
But for the state to require any dress code is an unconscionable violation of civil liberties and a grotesque imposition on the diversity of human behavior.
