First off, I'm not saying that kids are bad or that White people becoming minorities in their own counties is good.
I'm saying that if you have 100% ethnic purity in your nation, then having your population always grow isn't a good thing.
Do we want everyone living in 300sqft boxes? Do we want 30m super cities made of worthless materials sprawling our land?
For example, people are freaking out that Japan's birth rates are the lowest ever in the 20th and 21st century. If you do the math, that merely means that Japan's population if these birth rates continue will stabilize at roughly the same population Japan was at I'm 1900 of 45m people. That's fine. Japan doesn't need 120m people not does it need 200m or 300m.
We could all use with lower population. Of course, I want that lower population to include the lesser races and I don't want White people replaced by immigration. Those are separate issues. If we have the power to increase birth rates collectively as a society, then we have the power to deport all non-Whites and stop giving free gibs to non-Whites.
Has any other society accomplished this? No. So don't act like we don't need more people; population correlates with technological advancement.
What we don't need are *useless* people. We don't need niggers, we don't need people who kill all their time on entertainment, and we certainly don't need people using their energy to solve redundant problems.
We are all so used to both total material comfort and lots of wasteful people so we have forgotten that we are part of a collective and each members' survival depends upon a healthy collective.
