I'm a numbers kinda guy and I like statistics. That is why you can find a lot of references in my blog to news articles containing rankings, statistics, polls, etc. Here's another one. This article said that 7% of people didn't rate faithfulness as very important in a relationship. This was a survey of 2020 people, which means that 141 people said it wasn't very important. Who are these people?
Also, only 12% of people surveyed said that sharing political beliefs was very important, while 49% said that sharing religious beliefs was very important. I guess people feel that tenuous, otherworldly phenomena are more important than real-world, life-altering policies.
