I say this based on my own dejabbing experience: yes, there were some base, practical reasons, but also many complex, illogical feelings which explained why it took me almost six months to fully dejab.

Some of those same women are now "dejabbing" — removing it...

Dejabbers have become tired of the separation that hijab can lead to, of being spokespersons for, and defenders of, all Muslim women. They are choosing their own identity. As writer Rahat Kurd, a "dejabby," observes: "If we could just quit this protracted and demoralizing fight about women's dress and mobility in public space, we could get so much done with our lives."
