Could it be possible for both sides of a culture war to be wrong?
On the one hand, the Quiverfulls. If you peel back the message far enough, you realize that they're the Protestant* Christian equivalent to militant Islam. In fact, their mission statements often use militant language ("we need to win souls for the Kingdom!"). In that paradigm, children are not children, but future soldiers, clerics and babymakers. Yes, in this modern day most children survive to adulthood and will need some kind of vocation to make a living, but for YHWH's sake, the carefree childhood days are ephemeral; let kids have some fun!
On the other hand, the rest of the world. Society has degenerated to such a point that people are surprised and disgusted that babies are the result of sex, men and women dispose of relationships as easily as they do a condom, and LGBTQBOHICA movement is adding more letters and more ways to kindle God's wrath. The left and the L[regex]Q movement have created such a world of falsehood that up is down, black is white, hot is cold, and Christine Chandler is a TRUE AND HONEST WOMAN. When you stare at these abominations, you begin to understand why the QF's/Mormons/Islamic terrorists want to sequester themselves so they can create an army of believers who will wipe them out.
Then again, they Quiverfull movement has the Pearls and for that they can die in a fire.
*Catholicism has always been anti-contraceptive (think of the stereotype of 6 children as a "small" family) but have not really been about using their demographics to wage war, be it literally or spiritually. When Catholics did want to wage war, they just use Crusades.
