“Protecting religious liberty from gay marriage and protecting gay marriage from religious liberty”

Dale Carpenter writing at The Volokh Conspiracy:

How do we know when a belief is “religious” rather than a deeply help moral or philosophical one? How do we know when a religious belief is “sincere” as a opposed to pretextual? (In this regard, it’s easier to imagine an individual crafting his supposed religious beliefs to fit the exemption in response to a lawsuit than it would be to imagine a religious business or association credibly doing so.) Do we want courts deciding when a person’s religious beliefs have been “violated” rather than been made less comfortable? But while these are good questions, for the most part they do not seem particular to this proposal. They’re endemic in religious liberty law and protection.
