I wouldn’t put anything in the cake but I would make them wonder what is in their cake. I wouldn’t allow these scumbags to ruin me financially. I would pay a homeless drunk to come in and make their cake. The dirty drunk would be their baker.
As someone who reads the gay press & gay blogs, I can tell you that gays are VERY worried about what goes into their “wedding” cakes. Not a single comment goes by after an article about bakeries that some paranoid gay guy doesn’t chime in that gays better seek out other gays to make their cakes. It’s pretty obvious that they are trolling when they bother bakers with religious backgrounds - not actually seeking the cake. But I have nothing but sympathy for this religious couple who lost their business.
