Muhammad Haikal echoes and clarifies the arguments of the Singapore Hijab Movement:

Muslims are not asking for ALL women to wear hijab in ALL sectors, rather we are asking that for those ALREADY wearing the hijab, to allow them to continue wearing it.

By telling the Muslims that you are not allowing them to don the hijab in certain sectors, you risk further alienating them from the mainstream society. This would only perpetuate further the long held view of the government that Muslims are distinct and separate.
