I think that is definitely part of it. Abortions = NO new citizens = need for more workers to keep the system going. Same problem France/ Europe is having. We are, imho, a whole lot better off with Catholic hispanics coming up than Muzzies, like they have. I think this is why there is such ambivalence about this.
I find it interesting that one never hears about the dialectical opposite of 'Social Constructionism' (pdf) [beliefs are caused by social interests rather than justified by evidence and reason], 'Essentialism' [the shocking idea that an external world exists independently of our representations of it; that there is a human nature given independently of 'social constructionsism'], obviously social constructionism allows socialists to ignore nature and facts and thereby see and attempt to create their own reality.
I'm not unconvinced 'social constructionism' isn't the result of excessive pot or LSD consumption, as it was developed in the '60s.
This is the foundation upon which 'gender studies' rests and which allows them to try to recreate gender in their own image while wrecking all kinds of other pathological havoc on society.
Our schools are damaging our children.
