I would posit that the special privilege has been given to the non-religious, in that they have been able to openly discriminate against religious people in violation of existing laws.
I would suggest looking into the EEOC regulations mentioned by someone else in this thread and Title VII of the 1964 civil rights act.
Is it your position then that it's either your personal belief or a divine communication from your God that the government should be able to discriminate based on religious beliefs, against existing human rights legislation?
The exemption
> What should be the limit on someone's divine communication and the restrictions upon the government they live under?
None. But your definition of divine communication should not override otherwise unrelated rules.
