The problem is you’re wrong though, because legally you have to look at the lowest common denominator.
Imagine you are a baker and someone wants you to bake a nazi cake? Would you want to? Hell no, but saying that a producer is required by law to perform any creative production asked of by the client means that you as a Jewish gay person (hypothetically) would be forced to bake that nazi cake.
Similarly, it doesn’t really matter what’s “right” it doesn’t change that for some people, lgbt issues are considered religious sin, and they feel like they would be committing a religious sin in baking a pride cake. Now are they loony? Yeah they are. But it doesn’t change that you cannot force someone to artistically create something against their will. ESPECIALLY when you can just go to another baker who will.
