What I am seeing here, is that the women here, may Allah bless them, are using the hijab as a certain type of symbol. Something to distance themself with.
Would we have the same opinion about a miswak? Or what brand of toothpaste we use?
We should be conformed to the Qur'an. Not making the Qur'an give us permissiveness to do as we see fit. Granted, the Qur'an does not say wear hijab. I am of the opinion, that in the arabic, there is a precedent for it. Yet, I am not going to force it. More a personal opinion that I can keep there.
I respect the sister saying she felt better when she stopped wearing hijab. I mean you no disrespect. Yet, it was not the hijab, but what it meant to her. To me, this is a psychological issue and has nothing to do with exegesis with Qu'ranic passages.
Another of the reasons I am no longer a christian, was people who wanted the bible to give them permission to do something. A holy book is meant to guide us and inform our life, not because we think it is politically inconvenient or old fashioned.
Let me try another illustration. Let us say you arrived in a culture that believed in women doing all that was stereotypically male.. rude behavior, bravado and profanity. (just follow me here.. lol). Male and female were both of this behavior and no one questioned it. You arrive, as a practicing muslim.. wherein, women are respected, protected and cherished. They are modest and soft of speech. After a few years, the collective peer pressure will soon make her question the wisdom of her entire being.
I think the hijab is a symbol, yes. In today's world, it identifies one as a muslim. We should use that as a means for da'wah and as a silent expression of our commitment to our deen. Same with some brothers who chose to shave their beard or wear jeans and a tshirt. We are to not emulate those who are unbelievers.
I am not trying to argue, and I truly have enjoyed the discussion going on here. Alhamdulillah.
