Wearing a hat that does not hide the face is a harmless aspect of some religions. Suppose a law is passed banning hats indoors at gov't jobs. Some gov't employees are members of a religion that requires head-cover. They protest against the law.
Question: Are they facing a religion-based special penalty? Or are they seeking a religion-based special exemption from the law?
ANSWER TO THE QUESTION ABOUT BANNING HATS AT GOV'T JOBS:
Religion is irrelevant.
* If there is a valid reason for a hat-ban, there can be no religious exemption, else we have a 2-tiered legal system, in violation of 14A.
* If there is no valid reason for a hat-ban, the law should be repealed as pointless, not as anti-religious.
