I think the bigger, long term problem foreseen by the administration -- and basically acknowledged but sidestepped by the majority -- is how and where do you draw the line on what is a religious belief under the RFRA that justifies exclusion under whatever law we are discussing?
Saying that the owners of Hobby Lobby believe it is against their religious beliefs to have to purchase insurance that includes certain contraception options seems quite genuine. Religious objection to that is well known in our society and has been documented frequently, so it is not difficult to believe that their objection is genuine.
But what happens when the owners say, my religious beliefs compel me to object to having to abide by certain other laws, or parts of laws, that aren't so clear cut? For example, what if next time the owner of a company says "My religious beliefs are that men and women should not be working together, or that women should be child raisers. Thus, I am exempt from laws that prohibit discrimination in the hiring of women"?
Or, what if the owners say "I am a Jehovah's Witness. I oppose any form of blood transfusion. Therefore, I should not have to offer insurance that includes that."
Could get dicey.
