Nobody can make you take a good picture if you don't want to.

Fine, but that kind of response won't be applicable to the thousands of other kind of businesses that will have to deal with similar offensive "human rights" demands.

You may be correct about some business, but not all of them provide an instance like this where someones personal faith is being challenged. For example: if I owned a coffee shop I would not be telling homosexual couples that I don't want to serve them coffee because I believe that homosexuality is wrong. That's different than them trying to re-define the sacred (in my belief) bond of marriage. One scenario forces me to violate my personal beliefs (a "gay" wedding) and the other doesn't (exchanging my coffee for their money) as I don't find it immoral for them to drink coffee.

It really comes down to that issue. What they need to understand is that for every photographer who's personal beliefs require them to turn down a job such as this, there are probably a dozen others who will have no problem taking the job, so they are still free to have pictures taken of their "ceremony". Nobody denied them that right.
