Kind of looks like a "set up" situation doesn't it?
Someone deliberately looking for a baker of a specific religion in order to be refused?
Muslim bakers are most likely a tiny minority in this country, the vast majority are Christian. That's likely why less fuss is heard. The Muslim community is also much more conservative - I doubt a gay couple would look to a Muslim baker for their cake. Did this person SUE them? Has anyone sued a Muslim baker?
A baker that serves the public, should serve the public - regardless of who the wedding participants are as long as they can pay for the service and the requested item is within their ability to make. I don't think they should be forced to make anything lewd or pornographic.
Aside from that - there has also been a rash of cases of couples supposedly getting married and deliberately seeking out vendors they KNOW will be hostile to same-sex arrangements. I think that is wrong - maybe not legally wrong, but ethically wrong. In the original case, the couple sought out a baker they had used many times before and had good arrangements with, so they had the expectation their service would similarly be welcomed not rebuffed. Some of these other cases smack of set ups.
Conservative 'Comedian' Pretends to Be Gay, Asks Muslim Bakeries for Gay Wedding Cakes
Unfortunately for his thesis, several bakeries agreed to make the cake. At least according to his blog. But showcased are three bakeries that did not.
