Clearly you know nothing about me and my tv viewing, so why do you make assumptions about me? The baker does not make unique cakes. Prove me wrong.

Art is a distraction from the actual issue. 

Great, roll out that cake. What does it matter if the caked is rolled out to a gay or a straight wedding?
If the baker does not know, how does it matter? The baker is asked to make a custom wedding cake by a wedding planner. It is elbaorate and costly. It took a lot of time to make. Then it is used in a gay wedding. The baker has no idea. If someone tells him after the fact does he stop having pride in his work? Does he choose to be offended? 

The baker is choosing to be offended. That is not faith, that is being a whiney child.

If my cake is for a heterosexual wedding, then I take pride in that cake and it is a work of art.
If that same cake is used for a gay wedding, I no longer have pride in that work and it is not a work of art and I choose to be offended.

The baker is being a child.
