“Asians” in Britain already have a much higher birthrate than native English. Maybe 3 times the rate. On the bright side, so do immigrants, such as Poles, from the eastern side of the EU.
Imagined that is the case, but didn't know for sure.
There seems room to argue that substantially reducing world-wide immigration would tend to reduce international conflict. I.e., people in difficult areas would be required to confront their difficulty and eventually overcome it.
It does appear, however, that England is committing slow-motion national suicide.
