Too many welfare state supportes are also supporters of euthanasia and assisted suicide. Throw in the environmentalists who would be happy to learn that a new 100% lethal pandemic has begun will end human life and one can see that it will be a close run thing if Western Civ survives.
I think it's bigger than this. My wife and I experienced it when we had out third child. The looks of horror and incomprension about why we desired more than two children.
See, our first was a boy, and our second a girl. You would not believe how many comments we got about how that must mean we were done having kids. We had the whole set already. Having more was insane, selfish, masochistic... the flavors of distaste varied.
This goes way beyond the pro-aborts. It points a finger just as directly at those who choose to not have kids. And especially at those who disdain those who do have kids - especially in large numbers.
In my opinion, environmental based population restriction frequently gets latched onto by a lot of folks who are grasping for a reason to justify their own pre-disposed contempt for having children. But in the absense of environmetal whacko-ism, the disdain for having more than one or two chidren would remain.
This is a disease running rampant in the West. Europe and Canda have basically succumbed to it. The U. S. is the last great hope of resisting and recovering - and I believe that's directly linked to our greater retention of faith in God.
