As frequently annoys several of you, I think that economics should always and in every respect be subordinate to moral philosophy. I think that permits a great deal of freedom to pursue one's economic interests, whatever they may be. Still, when they come into conflict, I expect you to do what you think is right, not what you think is likely to make you more money. Those two things may line up, of course. When they don't, duty and virtue have priority.
I am thus inclined to view threats of economic boycotts if we do not surrender religious liberty principles as strong evidence in favor of the validity of the proposed laws. Similar evidence lies in the court rulings that bankrupt families which have tried to assert, however politely, their refusal to surrender their moral objections in favor of physical wealth.
It's not a question of agreeing with their interpretation of their faith. Some of you may; I know at least several of you do not. That is fine. We have room for disagreement.
What is important is the correctness of their priorities. When someone tries to use economics to force you to abandon morality, you are correct to stand on morals and refuse to consider economics until your moral concerns are satisfied.
The moral concerns themselves may be right or wrong. Under the First Amendment, that's not a public concern. Moral concerns arising from religious interpretations are for the religious individual to decide. Even if you think they are wrong to believe as they do, what they are certainly right about is standing up for what they believe is right instead of for what they believe will make them wealthy.
Those who would use wealth to subvert faith are not virtuous. Those who would use wealth as a lever to try to force others to abandon their faith and their morals ought not to win the day. Laws that strive to protect people from their machinations are wise laws.
If you really need a cake you will find that there are many more bakeries in America. If the wedding gift you really wanted was to force the religious to kneel before your moral opinions, that is a right you do not and ought not have.
