I dislike the gaudy weddings too, but do not judge those who can afford them and want them.
And I should have every right to determine what special products I will offer. If I as a Christian want to offer hot cross buns for Easter, I will sell the buns to anybody--Christian, Jew, Hindu, Atheist or whatever who wants them, but that does not extrapolate to me having to decorate buns with a KKK for the local Klan meeting. If I decorate a cake with dogs and such for the reception after the dog show, that does not extrapolate to me having to decorate a cake with fighting dogs for Michael Vick.
Freedom of conscience should be freedom in ALL matters of conscience.
