Looks like stores need prominent signs in their windows:
“Cake decorations/slogans do not necessarily reflect the beliefs of the management”.
“Yes I do love Big Brother”.
And of course, one could always go ahead and decorate a ‘gay marriage cake’ (remembering the signs one has up, and possibly praying a rosary or two or three for the conversion of sinners as one does so) and then go ahead and decorate a lovely 'Marriage is between one man and one woman" cake and display it prominently in the window of the shop. The gay marriage cake is going to be seen by maybe a couple hundred people at the ‘ceremony’; the ‘marriage is between one man and one woman’ can be seen theoretically by thousands passing by the shop, especially if it’s kept there for a few days. Every time a ‘gay marriage’ cake has to go out to satisfy Satan, bake another cake, “And God made them male and female”, etc., and display. . .
