Alceste,

The following retraces my earlier comment to some extent, I know, but I think that you and I agree.

The course of the debate for and against limiting the giving and receiving of services from the public sector while wearing religion specific items of jewelry or clothing, especially  face-obscuring clothing, further convinces me that legislation and administrative practices that purport to do more than to make it an offence or a basis to refuse service to interfere with one's capacity to wear such items:

(a) essentially serve to isolate and make observant religious minorities targets for further harassment and abuse regardless of the stated intentions or the good faith of those created the legislation or administrative practices in question, and

(b) cannot be fine-tuned to overcome the negative impact described in point (a).
