1) Illegal immigration is not about race, its about legally being in this country. So, don't let yourself get baited into a racial argument. A "white" from Europe, a "black" from Africa, a "red" from India, and and a "yellow" from Asia, are just as "illegal" as a "brown" from Mexico. [Too often--especially in large metropolitan areas--the apologists and pro-illegal alien crowd try to turn the debate into a racial issue.]
2) The US Constitution only applies to US Citizens. There is no such thing as a "right to a better life," or a "right to the American dream." These are not from the Constitution or even case law. They are propaganda sound bites from the pro-illegal alien crowd.
[There are some apologists who doubt this. OK Mr. apologist, give us some case law or any other jurisprudence that enumerates a "right to a better life," or a "right to the American dream" for illegal aliens . . . ]
3) If you are not in this country legally, you HAVE NO Constitutional rights. The US Constitution protects US Citizens--not people here illegally. This one must be repeated over and over again . . . [There are some apologists who are trying to put a religious spin on this one. Of course you can't just kill an illegal, of course you can't torture an illegal, these were extreme and poor examples for the apologists to use. My retort is to point out the obvious: illegals have no right to free speech or assembly (1st Amend), no right to keep and bear arms (2nd Amend), no search and seizure rights (4th Amend), and the list goes on. Look, I fully undrestand that for some of you apologists, the truth hurts . . . but always remember, you shall know the truth and the truth shall set you free . . .]
4) Illegal immigrants benefit from the taxes you pay. For example, if you live in Texas, especially Houston, a large portion of your property tax goes to pay for healthcare and education of illegals. Not-for-profit hospitals (funded by tax dollars) do not turn away illegals; AND, it is against the law in Texas for a school to ask for citizenship information. This message sent is: get here, and we will take care of you, and educate your children. [Many realists have pointed out--correctly--that my example is but a drop in the bucket. They are correct, the drain on the tax base by illegals is staggering. Most citizens would be outraged if they new just how profound and pervasive this drain is.]
5) If a person is born in the US, they are a citizen of the US. So, if two illegals have a child on US soil, that child is a US citizen, who can then provide a legal avenue for the two illegal parents to gain citizen ship.
6) The US has a quota system that allows X-number of people from various countries to legally/lawfully obtain citizenship. Prospective citizens get on lists in their respective countries. When their number comes up, they come over--LEGALLY. Some countries, like Mexico and the Phillipines have so many wanting to come here that the wait is 10-15+ YEARS. So, at least in the case of the Mexicans, its faster to just cross illegally.
