I'm pulling the stats out of my ass, but you'll get the idea.
20% of todays population are illegals, or are descendents of illegals. They represent the fastest growing segment of the American population. Additionally those fuckers are still crossing the border, and producing even more offspring. I believe 3 states are already occupied by a majority of descendents of illegals (Texas, California, perhaps Arizona?).
Our politicians (both parties) are doing nothing to curb the flow of illegals. In my lifetime I expect the hispanics (the vast majority of whom are descended from illegals) to become the domenent ethnic group politically, and once empowered they will drop all border restrictions with Mexico.
The year 2100: Hispanics 90%, Blacks 10%, White non-hispanics 0% because we've all fled back to our motherlands were global warming will have less of an effect. Lots of cold mountains in Norway.
Pure speculation on my part of course. But if something isn't done to stop the flow of illegals I'm sure my quality of life will suffer for it.
