It seems to me that cakes are a little different from other public accommodations in that they are artistic creations made especially for a pair of individuals. It would be like trying to compel any other artist to take on a particular commission.

I wonder if the argument will be a narrow one like this, or assert the broader rights of a “business to refuse service to anyone for any reason.” I’d feel differently if this were a local chain supermarket who refused to sell 100 off-the-shelf cupcakes to a gay couple for their wedding.
