If some Muslim women make the choice to wear the Hijab - respect it.  I don't care for tattoos, piercings, or false eyelashes, but choice is key.  Many Iranian Muslims have debated the Hijab extensively since their revolution in 1979.  Originally, it was a backlash against the Shah - who banned the head scarf offending traditional Iranian women.  It became a symbol of resistance.  After the 79 revolution, and then it became mandatory under Khomeini, and even the most active opposition faced the "whore" label if not opting to wear a headscarf.  It seemed to me that they equated the headscarf with purity.   Conforming to create "unity" is a central component to the Muslim faith. They pray in unity, facing the same direction while praying & fasting.  They don't pray the closet like many Christians.   As a westerner I would find it oppressive. But if a woman is choosing of free will - I respect it. If I can wear daisy dukes, or ride a bike naked, I surely can respect a headscarf on Muslim!
