The first point that sticks to my mind, is the issue of race. Mind you, I will be flamed and called names for simply posting something that I believe to be a factor that needs to be considered when discussing the issue of immigration in North America.
Western History is the history of one people being occupied and ruled by another (mind you, I am the latter, not the former). There is no history to this hemisphere before the arrival of the first Euro, be it Eric the Red, or Columbus.
Caucasians are not indigenous to this hemisphere, and that's a simple fact. When the first Europeans arrived here, a race of people were occupying the land, and living their lives as they saw fit to live them.
We (Europeans) knew that we were stronger, deemed them to be savages, and excused any actions we needed to take, in order to civilize them...even if it killed them.
We did exceptionally well in Cuba, we didn't let one single native inhabitant survive their initiation into civilization.
Here, we did a good job of marginalizing them by restricting them to reservations and such.
But the Spaniards didn't do as thorough a job south of the border. There may have simply been too many natives, too many mountains, and too many jungles to cover.
You see, I think one day, sooner or later, the native inhabitants of this hemisphere may simply start to ignore the ruling Euro-Americans, and move about as free as they used to before we got here.
There a very few countries, which have never been invaded, conquered, and settled by " others ". Even Japan's history is one in the same with this scenario; remember the Ainu ? The thing to always remember is, man , given 1/2 a chance, is now and has always been a wanderer; hence, an immigrant . Heck, it's even in the Bible !
Those fearful and screaming on about immigration and the destruction of this country, are what are called NIMBYers ! I don't like / aprove / agree with / whatever one cares to call it, ILLEGAL acts of ANY kind. But, legal and " impartial ", with NO " special favors " immigration , isn't a " hot button " of mine.
