Anyway, the case hinged on gay marriage not being legal at the time so the business owner was within his rights to legally decline the business. Now... whisk up people because you're all making whatever the hell sort of cake we order you to!
The real issue is how far does religious freedoms go and whether a person should be able to practise their religious beliefs as a business person. It's a question that will need to be answered eventually and probably will as time goes by and this conflict presents itself more often.
