The people opposing my common-sense views are probably part of a much larger problem: they are part of a system or group of people who secretly hate actual Americans and who want to slowly replace actual Americans by means of illegal immigrants. This is also happening here in Europe. They are building a system which is highly corrupt and where illegals hide and infest major cities, to the point you cannot get rid of these people anymore.
This isn't altogether inaccurate (especially not the corruption - we sure have a way of designing a government!), but it is important to come to grips with what 'replacement' is and why it keeps happening.
If you look back to Shakespeare's time, he wrote a play about a Moor in Britain. If you look at archaeology from 2000 years ago, there was a significant black population in Britain. So it seems like emigration from Africa to Britain has been going on a long time.
How long? Well,
Homo sapiens came out of Africa.
Homo erectus came out of Africa. Humans have
always been coming from Africa to the rest of the world, for as long as they've existed anywhere else but Africa.
Why is this? Because humans
evolved in Africa. Most of the species'
genetic diversity is in Africa. Every time the environment changes, such as a new disease, it's time to dive back into the gene pool and pull some uncommon allele out of the archives ... in Africa. And transmit it to the rest of the world.
Additionally, the non-African environments, colonized more recently, have a lower degree of competition for resources. To some degree, the longer lifespans and lower degree of violent conflict may be simply demographic in nature. It
is the perception of wide open frontiers that calls to people, in part. But good conditions seem to lower reproductive rates, making it even easier for others to migrate to a country.
Note, incidentally, that with all this migration, starting with no whites, people in northern Europe are nonetheless consistently white. That was natural selection, and continued migration would never alter that. However, white skin is now going to go away, not because of migration, but because of the discovery of vitamin D. People of any color can manage their nutrition and avoid rickets, while also avoiding sunburn and skin cancer. The destruction of the ozone layer has supercharged this process - with
most Australians getting skin cancer, evolution will relentlessly darken the color of that island.
For this or any other issue, a constant stream of genetic flow from Africa to the rest of the world is the natural and healthy situation for humanity.
