I am still waiting for someone to present a cogent argument as to how baking a cake somehow is forcing the baker to betray his faith.
It doesn't. Baking the cake wasn't the problem. They were asked to bring the cake to the wedding these two were having. Personally, I would have made the cake and said, "Get someone else to take it to your wedding, you got what you paid for."
They would have fulfilled their end by making the cake, and fulfilled their religious convictions by not taking it to the wedding.
And I will posit this:
If you ask a devout Christian to betray his beliefs, he will not. If you ask a gay person to stop being gay, they will not. Understand now?
