It sounds like you ignored the point completely and just switched to personal attack.

Do you agree or not that any law limiting hiring practices should be justified or not?

If so, how do you justify religion over other criteria that are personal choices of the candidate like style, cleanliness, politeness etc?

How do you even propose to discover criteria if you start with a clean list?

I generally agree about the business point, but you seem to belive religion has no impact on fulfilling one's duties regardless of the nature of business, which is dubious even in common important professions like doctors.
