The high birth rates among Muslims, relative to non-Muslims, is a symptom of rot in our culture. I blame the Protestants for warping the teachings of God on this matter. Until the Catholic Church, which Jesus founded, finds a way to get the minds of Protestants away from contraception we will continue to lose ground to the Muslims.
I don’t think that the unchecked childbearing of any element of society is the answer to this problem. Were we to encourage rampant childbearing within any group, we would soon be awash in low class, largely unemployable citizens. Never forget that the usable land area of these United States and of the globe itself is finite.
Or, a rot in their culture because they start raping girls as soon as they are fertile, giving them no choice in the matter of how many children they want.
