Holy shit....so you're saying they CAN refuse service to a Jewish couple or a black couple or an interracial couple.
He's claiming THE CAKE is the message...no writing on it...no male/male cake topper...no Star of David....no black couple or interracial couple cake topper
...not one thing on the cake that identifies who it's for.
Just the wedding cake. He objects to the act of baking a generic wedding cake for gay couples. How you can't see that as discriminatory is...baffling. I can't understand how you keep missing this.
