Agreed, and well said.
So if a gay national socialist wants a swastika flyer made by a Jewish printer, does the printer HAVE to do it because he is a member of a protected class?
Again, distinguish the job from the person.
I think these are the most reasonable arguments I've read from your side, but I think the concept of content "affirming" that they are gay could be stretched all to hell and become meaningless. There has to be some line beyond which a purveyor of some sort of custom product can say "no," even to a member of one of the oppressed groups of the moment. And that line can't be as simple as "protected classes" get whatever they want, as in my gay national socialist example above.
I'm not sure what you are even responding to, since I never said anything about sin, the Bible, or anything other than legal principles.
That is very interesting, and really makes me think about it differently. If there is no "content" to the cake for him to find objectionable, I think the case against him makes a lot more sense.
Regarding your gay national socialist example, you are complicating the issue by adding a lot more compelling circumstances. There's no reason to complicate this. At the heart of the matter is discrimination based on sexual orientation and this shouldn't be allowed.
Even if what the baker is objecting to is "content", he is still objecting to it because of discrimination against sexual orientation. If the baker is willing to bake a cake with "content" on it then he is opening his business up to requests of "gay content". If he denies the request because the "content" is "gay", then that's discrimination based on sexual orientation. He's free to deny requests based on reasons not protected by the Constitution.
