Bakers should just keep their mouths shut and make a damn cake that doesn’t taste or look very good and wash their hands of these douchbags. Don’t make the cake obviously terrible, but make it just bad enough that it’s on a par with, say, Duncan Hines. In fact, use a bunch of Duncan Hines cake mixes and cans of pre-made crappola icing off the shelves of Walmart.
Word would get around homoland that there are better bakers for their purposes.
That would not work either. More fodder for their side.
Just announce you no longer make custom cakes.
