So, even within Christianity, the Ten Commandments aren't precisely the same across traditions — the text is translated and even *numbered* differently.
This law appears to mandate the KJV version — a Bible translation entire Christian traditions reject. apnews.com/article/loui...
Except that they don't actually live by their commandments. They'll happily kill, lie, steal, commit adultery, rape, and incest, make graven images, work on Sunday, swear, and covet their neighbour's stuff. They just want to fool people into thinking they believe this garbage in order to get votes.
That's still Christianity. No Christian lives by all the commandments, and it's long been widely accepted doctrine that they will be saved through faith. They are living according to the expectations of their Christian community and traditions.
The fact that another person's religious convictions and practice don't make sense or are repugnant to you doesn't mean it's not real religion. Neither "religious" nor "Christian" is a synonym for "good."
