My concern is that the state is forcing a business to perform activities the owners do not want to participate in. How far does this extend?
What if I have an event business and I choose not to participate in 'Sweet 16' 'QuinceaƱera' or 'debutante' parties because I believe them to be culturally disgusting displays? Am I forced as a business to produce these?
If I am an athiest and don't want to participate in religious themed events? Don't believe in marriage at all and don't want to participate in producing marriage related events? Don't believe in Halloween and don't want to participate in producing Halloween events? The list could be endless.
This is an opportunity for the free market to create gay friendly marriage chapels if there is such a demand.
I suppose one option is for the business owners to shut down or move to another city or state where such meddling in private enterprise isn't an issue.
