People need to read the entire article. The article describes the costs of illegals and legal immigration. Read it all and you will see that it actually supports the positions most of us FReepers have on the issue.
The poster wishes to have a constructive dialog, supposedly.
A constructive dialog would involve opposing points of view that are factually stated, and the fact that he talks about LEGAL immigration and ILLEGAL immigration as if they were the same thing makes the whole point invalid.
Most thinking people are not against immigration, but ARE against two things:
1.) Illegal immigration
2.) Legal immigration policies designed to destroy the host country by excluding people who may possess marketable skills but do not have the right skin color or heritage, preferentially accepting people who have no way to contribute to society but have the right skin color and right heritage, and doing all this in numbers that are meant to place enough of a load on society to break it down, which is the end goal of the people who have put these policies in place.
