Correct, but you fail to grasp the following simple concept; the Sikhs had a problem, namely the wearing of a turban and the need under British law to wear a chrash helmet. So, being the tolerant, welcoming people that we British are (and not the racist scum the Guardian and other leftwing rags constatly claim that we are) a law was passed that they can be excused, if they are wearing a turban.
Now, that is the solution offered; and should a Sikh wish to take that option he can, but if he demands a diffferent solution, despite the fact that the exsisting one has been ruled to be perfectly acceptable, then he'd be told where to go. This is what this girl wants.
There is a uniform for female Muslims to wear, this addresss the problem of female Muslims and school uniform.
