I believe 3 out of all the bakeries he spoke with offered to bake a cake but not decorate it with the words "Gay Marriage is Wrong". They just outright refused and found it offensive. But you seem to miss the irony completely. The one asking for the cake doesn't see the phrase "Gay Marriage is Wrong" to be offensive as it is part of his religious beliefs that traditional marriage is holy matrimony and some faiths believe it to be one of the sacraments. He was denied a service over his religious beliefs. Yet a person whose moral conscience doesn't want to do gay wedding cakes is forced to under fear of jail, fines etc.
While surfing the web today, I discovered there are lawsuits against gay bakers who refused to provide a cake that did not support gay marriage.
One such case was an order for an open Bible with this symbol placed on the cake.
The gay baker refused to do it. Now there are cases in our court system of gay bakers being sued for denying a cake with a Scripture pertaining to sexual sin or symbolism
You see, I think the gay baker has the right to deny a service that offends them. But I also believe those of religious convictions where gay marriage is an abomination to their faith should not be forced to create something for a person that they find offensive.
