Indirectly dehumanizing a woman for her expression of her cultural identity does little to remedy the illusion of oppression. What would be empowering about that? It wouldn't be much more useful than slut-shaming women for feeling compelled to wear makeup. Women wear a hijab for a multitude of reasons, some of them cultural, religious, or personal. But banning them or demonizing them has done little to promote progress for the better treatment of women. (You'd have the opposite effect, anyway, as people tend to double-down when their identity is being attacked.)
In regions wear women are oppressed, it is not tearing off their hijabs or burqas that would liberate them; it would be things like education, laws that protect women, and having places where women can feel safe that would do astronomically more to empower women. Ultimately, it is what women want for themselves that takes precedence, which won't take the same form in every society or time period. Period.
