Common sense? Sorry, but when it comes to forcing a baker to do a special to order cake completely outside his regular repertoire of for sale cakes then this is for me totally down to artistic freedom. If someone then sues for such a reason that is a frivolous lawsuit and if it were down to me the one who makes such a lawsuit should pay for both his and the other sides legal cost plus a punitive fine for the business the company has lost due to that frivolous lawsuit. But that is just me.
I may be very anti-discrimination on regular orders but when it comes to insane demands from a baker/other business then that company should be allowed to refuse such a service. Regular service from the regular book of stock items (or stock for that business) should not be allowed to fall under "artistic freedom". Now if that person wants kissing men on the top of that cake then a company can be allowed to refuse that part of the order, they do not sell that kind of a thing so there should be no reason to force them to do that.
Sorry, but that is just how I feel.
Hey, and if the KKK/Storm Front would come to my bakery (if I were a Jew or black) and would ask for a Hitler cake I would say that I would bake them but that this is a special order so I would make them a quotation for 10,000 dollars. I would make that cake but due to me not wanting to do that (and it being not a regular cake that I offer in my shop) then it is my freedom to ask what I want. I would have to hire another bakery, special staff for that day, fly in that staff, etc. etc. etc. for me to make such a cake, extra another 1,000 dollars for delivery (because I would have to fumigate and completely change the interior of the truck I would use to make such a delivery and hire the Black Panthers for security (or some Jewish organization like that). If they want to pay that then I will make them that cake (laughing my behind off while I order it at a bakery somewhere they do not have a problem making such a cake) and then laugh all the way down to the bank.
They want to buy a specially created/artistically designed cake that I do not make or create, then they can pay extra for it (a lot extra if it were up to me).
