There are always exceptions given for all faiths in every aspect of society.
There always will be those who don't agree with them either in principal or when applied to a certain group.
Take sharia law as an example, It's the oft repeated "they will/are/have imposed their law on us" and although it's true sharia law runs alongside the law of the land and many minor disagreements between Muslims are resolved in sharia courts (Divorces/Property disputes etc), It doesn't undermine English law as that is applicable to all regardless of if they like it or not.
Now it's plainly obvious that this whole issue (and things like halal/mosque building etc) gets whipped up into a frenzy by newspapers, facebook groups and political parties to suit either their long term agenda or just to shift a few papers with an attention grabbing headline. The fact is, there is no compulsion to use the sharia court, you can go have a regular ordinary divorce or civil action.
An almost identical system of religious courts has been running in the UK since around 1700, It's called the Beth Din and its the Jewish version of shariah courts. for some reason newspapers seem to shy away from publishing headlines "bashing" Jews, perhaps it would evoke some dim and distant ugly memories if they did.
So if a nurse fancies her sleeves down when she isn't actually treating anyone as far as i'm concerned it's cool.
If Mr Singh wants to ride his crotch rocket with just his turban and his faith in Guru Nanak to protect him i'm equally happy.
If the papers had a genuine interest in clinical/patient safety and preventing the speread of MRSA, they'd do better to draw attention to the privatisation of hospital cleaning services by NHS trusts rather than some tiny little exception given to the 1 nurse in a million who may want to roll down her sleeves.
lets face it if you're a surgeon and a Muslim woman, you've overcome the gender bias that exists in Islam, you're stood in a room with lots of other men who aren't your husband/brother/father without a chaperone. It's fairly safe to assume you're wearing scrubs and a mask.
