Perhaps it should be. Why, though?
Because you injected race into a discussion regarding religious views when the particular religious view at issue is unrelated to race.
So, back to the question asked that you avoided: What do you think of a Miss White USA, Miss White Mississippi and Miss White Teen pageants?
So you think as long as there is no law against discriminating against women it's fine
No. But in this instance the discussion is about compelling individuals using written statutes, otherwise known as "laws". Hence in this case the discussion is about illegal forms of discrimination and not legal forms of discrimination.
If we are going to leverage laws to affect social change then it's only fair for judiciaries and legislators to provide clarification and time to comply for choices that have historically been left to personal choice. If a law is going to prevent a certain type of discrimination then it should be written to make that specific type of discrimination perfectly clear before someone is punished with that law. If the judiciary is going to establish common law where a statute is unclear then time for compliance should also be provided prior to issuing punitive measures.
