Actually, some of the articles quoted in this discussion interviewed fired girls who insisted on wearing hearscarves at school against the advice of their parents. Maybe in a link from Wikipedia I also read of an example from before the ban in the nineties when a girl became an obvious "born-again Muslim" fundie (the same way boys do), and even rejected a compromise offer allowing her to wear a headscarf but calling on her to attend science and physical exercise classes. This latter case indicates to me that there are other ways to identify forced or voluntary fundies than enforcing headscarf bans with zero distinctions and a threat of expulsion.

It's about enabling an environment where a girl's worth is not defined by wearing a headscarf or not, and where nobody has a right to make assumptions about her sexuality depending on whether her hair is visible or not.

That sounds nice, but by having headscarf-wearers expulsed, the ban assuming all of them to be proselytizing fundies, and switches the onus of neutrality from the state to the citizen (perhaps you missed this).
