"And sometimes new judge life is about standing up for yourself and what's right."
I s'pose it depends on what you consider to be "right".
The school's rules required sensible haircuts and sober coloured hijabs - there is nothing even remotely unreasonable about either requirement, and there most definitely isn't any "ism".
Also, I know the 'correct' thinking at the moment is to despise our past for fear of being labelled a racist, but what's wrong about learning about England's white kings and queens? (white before kings and queens is surely unnecessary, unless there some non-white kings and queens I'm unaware of). White kings and queens are important to our history.
It's a bad move of the school to have caved-in, although I suspect it's the siht-scared governors rather than the Head, as now anything these children feel they want changed will result in protests.
These children are going to have a very rude-awakening when they enter the real world, where their childish antics won't be entertained.
