They know and understand people are going to have Sex. They Fear extreme High Population. So perpetuating Sex (which is gonna happen anyway) which will not cause Pregnancy is encouraged. This is not Hard to understand. Big Business and Big Government have one thing in common, Perpetuate Personal Selfishness (hence the destruction of Morals through Perversion).

But,You never noticed Big Globalists have not problem with Abortion, Prostitution, lowering the Age of Consent?

Just Fulfilling the Promise of Feeding , Clothing and Shelter is getting harder in all places (especially when the Government is doing it ex: China)
China's former Chairman Hu Jintao told George W. Bush on a Trip that If China does not Create 25 Million Jobs every year, the will have Civil War.

The New Philippine President Rodrigo Duterte wants a 3 Child policy in a Place that's most like the USA in Asia (Similar to China's One Child Policy)...
Imagine Either Hillary or Trump saying that?
