Oh wait, that's already happening and it's got a court ruling backing it: http://www.wsj.com/articles/court-rules-baker-cant-refuse-to...
Who is the "homosexual bigot" in your example? The judge practicing the law of the country ? Per U.S. Declaration of Independence, "All men are created equal".
If you don't like gay marriage, that's great, don't get one! Go to a church that doesn't recognize them!
If you do like gay marriage, cool - go get one!
Either way, call yourself married! Or not! Fortunately the government can recognize things like shared decision making, inheritance, property ownership, etc. without having to recognize that some people held a ceremony and a party and others didn't.
There is no crisis where gay couples are unable to find wedding bakers and photographers willing to serve them. I personally have no problem with homosexuality and gay marriage. But someone with religious convictions against it, should not be compelled to be involved. It's totally wrong to force a devout Christian photographer to participate in a gay wedding if he is opposed. What entitles you to his labor?
...partly because laws were introduced to prevent discrimination by people offering commercial services.
