It makes perfect sense if you are an atheist writing the show. That is their message to people of faith, that everyone will be happier in the end if you just put your faith on a shelf and forget about it. That’s their homily to you! The show, on false pretenses, gains access to people of faith, to preach this message to you.
It also reinforces the non-believer that those annoying people in your life who are people of faith really just need to change their attitude and everyone will get along.
