Gabriella,
Just out of interest, does teaching children assertions as facts when the teachers cannot know them to be facts in a school environment not concern you at all?
I wouldn't say it doesn't concern me at all.
In this country, given the evidence of increasing costs of living not matched by a rise in wages, falling religiosity and the change and apparently increasing diversity in religious interpretations, I would be more concerned about exam results than the way religious or moral or cultural beliefs are taught.
I would weigh the concern about a particular school's religious or non-religious ethos against the evidence of whether a particular the school provides good exam results that would potentially lead to more job choices for its pupils, especially for those girls who might be disadvantaged because they might feel less inclined to take the employment risks boys might take for a variety of reasons:
E.g. those girls who might be influenced by the limits of their physical strength to not apply for or not be as good as a man in certain jobs; or where the greater risk of sexual assault compared to a man might influence some girls to not take jobs in remote or confined places where they might be physically vulnerable, or those girls who think they might run the risk of not being employed because they are of child-bearing age and employers might assume they will potentially have health complications or just be less mobile and more fragile due to future pregnancies, or think they are more likely to focus on child-rearing than a man; or those girls who might be influenced in their job choices by the risk of being employed because they are attractive to the man interviewing them and the risk of having to decline his advances without risking their career advancement, or who worry about the risk of taking career breaks due to maternity leave or the risk of missing out on career advancement because of a maternal urge to spend time nurturing their children while male counter-parts devote as many hours to delivering on work deadlines and gaining valuable career experience that makes them more capable in the job.
I think those girls might be more concerned about their academic education than whether the school teaches them religious or non-religious stories about morals, that they might discard as they grow older and gain more independence and freedom.
If a particular faith school is not delivering on education that will give pupils greater choices, then I have no objection to it being closed down or modified. My husband was keen to send my daughters to a Muslim faith school because of the ethos but I was against it. The female Muslim teacher who taught there, and who was a family friend, also advised me that if I was interested in my daughters receiving a good academic education, non-Islamic schools were better suited to achieving that outcome.
