I don’t think for one moment that just because our government has ignored illegal immigration for the past 50 years that we don’t have the right now to stop it or even reverse it. We may not have enforced the laws, but we are not the ones that have broken them.
Just because no trespassing signs are ignored, do not give anyone the right to trespass. Illegal aliens have ignored and broken our immigration laws and now we chose to stop illegal immigration. We made those laws and we have the right to enforce them. This is 2007, not 1900 America and we cannot absorb millions of poor people added to our already overpopulated country. It will destroy us economically and socially. We cannot afford uncontrolled and unlimited migration.
What happens when a species grows out of control, nature takes over and thins it out in order for the species survival. Plants or animals. Over-population of plants, animals or human threatens the entire survival of the species.
