First of all, if you don't have children and you are white anglo, you are helping the muddies breed you out of existence. Because your "govt" wants to flood your country with brownies and low IQ subhumans, it's imperative that you procreate, as those muddies will definitely have many many children because they bring in welfare.
But, here's the thing: If you cant wait about 3-5 years before having children, you will likely be able to take advantage of IVF instead of the crap shoot it is today. IVF is on the verge of being so cost effective, that you'd be a fool not to use it.
Btw, this isn't science fiction. We already have a handle on many of the genetic sequences for complex traits; hair color, skin color, height, bone structure, eye color, etc. In the next 3-5 years, we will also have a handle on IQ.
It goes like this: Your woman goes to an IVF clinic, is stimulated with hormone therapy, and produces many eggs (embryos). Those embryos are then sequenced and frozen. Once sequenced, you will know which one will be the tallest, which one will have blonde hair, which will have sub 100 IQ, which will have 130+ IQ, etc. Then you only thaw the one you want, and the tail risk is eliminated. No more down syndrome. No more rare genetic diseases that we are carrying around.
Some will call this eugenics, but that just means "good genes". Eventually, everyone will do this, and we will eliminate all the unwanted outcomes that come along with natural fertilization.
Again, this isn't science fiction. Everything I've said above is either happening right now, or will be possible in 3-5 years for just about everyone who wants to partake.
