Of course you're not interested in my post, emily, because you're not interested in anything that derails your pre-conceptions and dogma, despite your own acknowledgement that you have little knowledge of Islam.
I am happy to send you links to the academic articles that support the assertions (hardly really an assertion, that the Qu'ran is a revealed text, or that the gates of ijtihad were closed, but never mind!) made in my post - written by Islamic scholars (primarily Hanafi, but all schools are represented) - though some of these are only available in Arabic, which I appreciate that you might not be able to read: though I honestly don't think you are actually interested.
I genuinely don't think you want to deepen your own understanding: you want to read things that support your world view, and either ignore or attempt to discredit anything that disagrees with this. That's your right - we live, thank goodness, in a free society - but please don't pretend your disdain for factual and intellectual arguments makes you somehow superior.
The issue off face covering, whether by burkha or niqab, is interesting in the Pakistani context, as apparently, it is becoming far more frequent in areas around Peshawar: it serves as a real source of irritation, apparently, to some of the Afghans living in the region! The FATA area of Pakistan has traditionally been much more conservative than the rest of Pakistan, apparently, and one of my students told me that she has experienced being beaten around the ankles whilst getting on a bus, because her burkha rode up as she climbed the steps, and she wasn't wearing long, thick socks. This was last summer, and on one occasion, so I don't know how much one can generalise from this, but she also commented that her grandfather, an imam, is becoming frustrated with some of his daughters-in-law who are insisting on covering their faces, against their husbands' wishes, because he sees it as an Arab tradition seized on by Peshwaris to demonstrate their piety, rather than a religion tradition or obligation.
Those of you who have mentioned Wahhabism and salafiyya might also be interested to google more about the Deobandis: this is a sort-of equivalent movement, but in an Indian sub-continental context, and grew up around a similar time as the various salafi movements in the Arab world, towards the end of the 19th century. It's important - and interesting - because, despite Wahhabi funding for many UK Sunni mosques, many of the preachers and imams that same funding provides support for are actually Deobandi rather than Wahhabi.
