Why Cakes?

Still trying to grok what commandment Christians think they are breaking by selling a wedding cake destined to be eaten by sinners at a wedding of sinners. Isn't that the fate of every wedding cake in history? Because in Christian theology, everyone’s a sinner, not just people who approve of love between any two people in the world, but also those devout individuals who check first to see who's loving who. The most God-fearing bakery store owner in the world is a sinner, too, even on their wedding day. I’ve read the Bible several times, and parts of it many dozens of times, and I’ve never seen that believers are expected to go about making it hard for non-believers to do any of the things non-believers do. Every kind of person in the world eats bakery items — businessmen, doctors, grandmothers, pedophiles, internet spammers, pastors, nudists, sex traffickers, congressmen...it’s a very mixed bag! If it apalls God to see his children providing delicious baked goods to people who go to a different church than the baker, or no church at all, Christians need to get out of the bakery business. But if it’s fine with God for a Christian to sell baked items to some kinds of sinners, why not every kind of sinner? Is there a list somewhere in the Bible of behaviors that Christians are told to stick their noses into, while not sticking their noses into others? I don’t think there is. I think this notion of making a big stink over a few of the choices people make but not the millions of others is one that Christians — rather, some Christians — have come up with on their own. It's not often that people can say they've come up with a policy God should have included, but for some reason didn't. I wish these devout, modest souls would let themselves takes credit for this one.
