I was thinking about this the other day, and in the U.K. there are a lot of people who would say they are Christian if asked their religion, but really they are non-practicing or more likely atheists, but don’t want to admit it.
I saw a statistic once where they asked people whether it was true or false that one can only be moral if one believes in a higher power, sorted by country. The highest numbers reached more than 90%.
With this in mind, things like your point make a lot of sense.
