Supreme Court Rules In Favor Of Colorado Baker

[Clueless Morgan]

I know there's a different discussion being had here right now but my basic question with this ruling is this:

How is a "gay" wedding cake sufficiently different than a "straight" wedding cake such that it affect the baker's decorating ability? For example, a couple comes in wanting a white wedding cake with a cascade of sugar flowers in golds, yellows and violets. How does whether the couple is gay or straight affect the baker's ability to artfully arrange sugar flowers? Where in the creative process of designing that cake does the gender of the people getting married affect how to arrange the sugar flowers or smooth the fondant?

Is this a silly question? Because I can't think of a way in which the two cakes would be different...
