jno - //so their problem was in accepting the order but then changing their minds - and saying why? //
No, their problem was breaking anti-discrimination laws. The reasons why are not the point in law - breaking the law is what counts.
//Harsh, I think. After all, they got the cake they wanted from someone else, but presumably decided to celebrate their wedding by prosecuting a bakery. //
I don't think their celebration and the prosecution would be connected, it infers a nasty vengeful attitude on behalf of the couple.
As I see it, gay people spend enough of their lives suffering prejudices on a daily basis, without someone breaking the law to point out their disapproval of gay marriage.
// And the moral for the bakery is to shut up about their beliefs and lie about why they can't make a cake. //
No, the moral for the bakery is to realise that breaking the law to enforce their beliefs will not be tolerated.
As I have advised, a little common sense, coupled with a level of tolerance and understanding that is the cornerstone of Christian belief, would have avoided this issue coming to court in the first place.
The fact that the bakers appealed and lost would appear to demonstrate that they perceive that their beliefs allow them to flout the law of the land - they do not.
