Is there 'punishment' for these people if they baked a cake for a gay couple and didn't know it? Would 'god' be like "hey hey now, I see you tried to slip one under the door there, nope, not gonna do it, wouldn't be prudent at this juncture". Or would they still get through the pearly gates thanks to their ignorance? What if they were cupcakes? What if they baked a cake after eating fish on Friday? Or maybe they walked past a homeless person without helping 'the least of these'?
Look out for that slippery god-slope. Maybe he will be sitting there in his chair after they depart and are about to enter heaven and say to them "hmm, just going down the list. Oh! I see here you judged others while on Earth, even though I told you specifically that that was reserved for me alone". "And, by my reckoning, you sinned 5,894 times and I had to forgive you. But you for some reason couldn't forgive two of your brethren, whom I commanded you to forgive, even once. You know I am normally a very forgiving soul but when people who claim to follow me in fact ignore most of that book I gave you, I just get a little judgemental. Which I am allowed to do wouldn't you agree? So I'm sending you for all eternity to bake cakes for Lucifer. He likes Devil's Food."
