How do you feel about a bakery that refused to do a topping for NAZIs or KKK groups?
Do you think that they have the right to NOT be forced to decorate, say a lynching? 

One thing that I saw that shocked me is that the baker did NOT deny them a cake. 
He simply refused to decorate the way that they wanted (Im guessing that they wanted a groom/groom kind of thing on top). 
In addition, he was the ONLY person doing cake decoration at that place. 
But, there is absolutely no reason why they could not buy the cake and take it elsewhere to be decorated.
