if you think a woman chooses to dress that way you are fooling yourself.
I am sorry that you can be so arrogant and full of yourself thinking you know all the facts while, judging from your post, you know almost nothing about Islam, let alone the concept of dressing and general Islamic jurisprudence.
I can say with 100% certainty that ALL of muslim women I know of who wear hijab, ALL of them wear hijab out of their own conscience and free will and NO ONE forced them too.
And I know personally at least hundreds of these women, including my own mother, sisters in law, aunts, cousins, etc.
I was born and lived most of my life in Indonesia, a majority muslims country (in fact, the country with the most muslim population), but it is, unfortunately, largely a secular country.
when Indonesia was still under Suharto regime, the government banned the wear of hijab in ALL public institutions, including schools, government offices etc, because the regime (who was modelled after a combination of Turkey "modernisation" and military dictatorships) was afraid that Islam would get really strong and hence challenge the authority of the regime.
When I was in high school, a few of my schoolmates decided that they wanted to wear hijab out of their conscience in defiance of the school rules, and as a result they got EXPELLED from school. That's how much they were willing to sacrifice to implement islam in their life.
In fact, not many Indonesian women wore hijab during suharto regime as a result of the "modernisation", but slowly they came back to the Islam and now more and more women are wearing hijab as more people returned to apply Islam in their life.
