No, the baker wasn't hired by the queers. That's a lie. The queers targeted the Christian and tried to force him to submit to something he doesn't believe in. Now go ahead and prove your accusation that the baker would sell a cake condoning adultery. Your fantasy isn't reality. Go ahead, prove it.
If you have a business that is open to the public there are laws against discrimination. Just like white restaurants have to serve black patrons. The owners may not believe in mixing of the races. They can have those beliefs in their private life. But a business open to the public cannot discriminate according to the laws.
It doesn't matter if they targeted a Christian baker. The Christian baker has a business license and is required to follow the laws. What made it a huge deal is the fact that the baker pitched a hissy fit. If they had simply baked a cake, collected the money, and ignored whatever nonsense was involved, it would not have been anything but a business transaction. The baker has a business license to bake cakes for money. There is no religious belief involves in baking a cake. It does not mean they participated in the wedding or condoned anything.
You don't think they have had any customers say this was their 2nd marriage? Or had a pregnant woman buy a wedding cake?
