Norm, you are injecting beliefs into constitutionality, which have little to do with beliefs. It is interesting that one of the first cancellations was a convention for the Disciples of Christ who regarded the law as unchristian. But, that doesn't address constitutionality either. You are totally entitled to your beliefs, within the confines of your home. As soon as you establish an enterprise governed by interstate commerce, you have brought yourself under the umbrella of the constitution. Historically, with other topics, the courts have interpreted that your beliefs are limited by the rights of others. Eventually, Hobby Lobby will also discover this.
syb: I'd suggest you review the First Amendment to the U.S. Constitution.
