Those stats are garbage. 99% of women who have less than a handful of sex partners are likely only that way to due to devout Christian faith and thus highly unlikely to get divorced anyway.
What kind of logic is that? The point is that unchaste individuals make for bad spouses. It doesn't matter whether they're Christian, Muslim, Hindu, or from the Moon.
Come to think of it, the whole thing is pretty self-evident, even without any "studies".
And I want to add one more thing: If you're a man and promote or exploit this behaviour (ex. "game"), you're acting at least as foul.
I just think it's stupid for people to claim that Christian, "prudish" values still hold sway over people when every facet of popular media, every single bit of it, promotes open sexual relationships with earnest.
They do hold sway over some Christians, as far as I know. And what's bad about these values? I applaud the effort to live by them. At least they show some backbone and make use of their free will.
