I have mixed thoughts on this subject. My daughter is a lesbian married to a transgender woman. They have already been subject to employment discrimination (in Oregon for crying outloud! A lawsuit is under way). They do not need any more such treatment.
On the other hand, I do not believe the government should be ordering people to do things they don't want to do. Ask yourself a question: if you're planning a wedding do you want to put it in the hands of people who are doing it only because the state is threatening them?
