Your "Africa link" is now being dis-proven as we speak. Modern science always looks for the easy way out, and that is their way of saying, "this is too hard to figure out, so we'll just say that modern man started here and end the debate", well, there is a new debate raging in light of recent evidence that predates any ethiopian, or african culture by hundreds of thousands of years, not on the dark continent, but at the poles of all places. As for the immigration issue, there comes a time when a nations soverignity has been declared and recognized that immigration must be curtailed so as to not outstrip the resources of that land. Also, it would be wise, if people wish to enter a country, to try to assimilate. Learn the language, customs, and embrace that culture. Show some patriotism, in other words, for their adopted land. One should not expect their hosts to learn their language, customs, and morals,(or lack of), nor should they expect a free ride on my dime! The ones who would enter illegally are nothing more that leeches who want to screw things up in this country for people who have to bust their butts to make ends meet. Each illegal in this country now costs the average tax payer plenty, yet, more sneak in each day. I for one, applaud states that are finally showing the intestinal fortitude to turn the lights on these cockroaches.
