I will adress one aspect about the Bakery case. In this instance they would have their hand specifically in the event, also not to forget the photographers who have been sued for not filming a gay wedding. There is a difference in baking a cake and selling it to someone or refusing to sell, and making a specific cake with a specific message on the cake (whether it be 2 female cake toppers or 2 male. or congratulations Lisa and Maureen) the difference is one selling a good, where the other is more like catering to a service.
Put yourself in someone elses shoes--suppose you have JW's that frequent your business, you gladly serve them cakes, then one day they want you to bake a cake and put on it (Happy 140th anniversary Watchtower Society) I am sorry, (well actually I am not), but there is no way I could do such a thing, and I would have to speak up out of religious beliefs that I can not cater any event that celebrates the longetivity of the WT Society. I could not in any way shape or form be a partaker in anything that promotes the WT Society. For as ever much how wrong I believe the Watchtower is--there are just as many people who believe that gay marriage is just as wrong and don't want any part of it.
