I question the wisdom in general, of forcing anybody to bake anything for me against their will. A wedding cake is intended to be eaten.
Militant homosexuals need to think twice about their strategy in this. Baptists might pray over it. Catholics might put holy water in it. Less moral, less charitable people might adulterate it in any number of unpleasant ways.
It might just be that none of the above would put the level of skill and care into a cake baked under forced servitude, that one produced freely would receive as a matter of course.
This wasn’t done for believed wisdom’s sake. It was done to raise an evil cause.
