In general I don't think people should be forced to do things by the government (particularly when we are talking about a secular government in a pluralistic society) that go against their moral views, whether it is religiously based or not. I say that both about things that we are against, and things which we are for.

So for instance in the latter, our religion accepts the lawfulness of polygamy. Say though someone went to a baker for them to bake a cake for their wedding to their fourth wife, but the baker refused because in their view polygamy is unethical (forget about the legality in this example, pretend it was legal). I would likewise argue that in this case the baker shouldn't be forced to provide their service for something they consider immoral, even though from our perspective it isn't. Of course the customer who has been refused is in their right to then not give them their business and let others know of their refusal of service, but there's something unsettling about the person being forced by the government to violate their ethics to conform to some secular government's mandated morality into performing an action that goes against their own beliefs. Now it's a different question of course if the person works for the government, in that case the government is their employer and as such can tell them either do what they're paid to do or look for another job. But in the case of a private business, it should be up to them who they wish to provide service for or not, and as such reap the consequence - good or bad - of the lost business.
