I don’t know...maybe it’s just because I have kids and I don’t want to them have to live in a country and a world overrun with people that are basically barbarian - which HAS TO HAPPEN unless DRASTIC steps are taken (either make more babies here, or delete lots of theirs).
And I am willing to do what is necessary to reverse the past social engineering...even if it looks like sacrificing conservative values.
Getting into a breeding contest with Arabs and Central/South Americans and Africans is hardly the way to ensure a civilized society for your children to live in after they’re grown up.
Clamping down on immigration from underdeveloped and/or unstable countries to developed and stable countries, should be a high priority. Those populations’ growth rates would naturally slow, if we weren’t providing a release valve for the pressures of their excessively high birth rates, just as the population growth rates of Europeans in North America slowed drastically when our ancestors hit the end of the frontier. Other countries’ borders need to serve as the “end of the frontier” for populations that are growing (and behaving) like feral cats.
