There aren’t “Christian” bakeries. There are just “bakeries” — and they use public roads and police and fire services and as such need to serve the public. And you would be surprised — Lots of Islamic owned businesses sell liquor even though they are not allowed to have it. They are just in business to make money to raise their families — they don’t need to treat other people badly to make themselves feel superior. That’s why you haven’t heard of any. Try to not so be narrow minded.
