He didn't ever refuse to design a cake for gay couples.  He just doesn't want to design a wedding cake that would go against his religious convictions.  Someone suggested that Jack Phillips could decorate a nice, artistic cake minus any evidence that it was for a gay wedding.  Then the couple could place whatever items they want on their cake to signify to their guests that they are at a gay wedding.  Can you live with that?  I can and I bet Jack Phillips could as well.
