When you get into a discussion with one of those heavily indoctrinated teabagger - Lou Dobbs fans that rant on, and on, and on about how the Democrats are trying to guarantee that all the illegal aliens in our country will have free health care ... toss the ball back into their court.
Ask them, "Why do those illegal aliens come to our country?" After you've received the answer, which you obviously are already aware of, the one that states they come here to work and to get free health care, etc., etc., then is the time to spring the trap. You tell them that Congress has already passed all the laws necessary to ensure that the illegal aliens don't get free public services; the reason why they DO receive them is because of all the right wingers that are NOT doing THEIR jobs.
Update ------
It seems I didn't explain myself as well as I thought I had. I am NOT advocating for turning anyone in to the authorities. What I hoped to convey was that such an argument might make the Lou Dobbs fans realize their own culpability in what they've been led to perceive as a problem. If they see that, who knows what other truths you might open their minds to.
The key word here is ... illegal. Tell your right-winger debate partner that the "illegals" are here because he/she, their brother-in-law, their bowling partner, their gun club buddy, or maybe their own employer is hiring them. If they are aware of an illegal alien living, and working, in this country it is their duty as an American citizen to report it. If they choose not to, then they are an accessory after the fact, and are thus criminally liable.
If everyone that hires "illegal" aliens were held accountable and had to pay the fines and serve the time that our current laws provide for, I can pretty much guarantee you that the flow of "illegals" into this nation would end very rapidly, and those that are here would go back to where they came from. Congress has already made it "illegal" for those people to be here - that is why they are called "illegals." Congress does NOT have the authority to ENFORCE the law, only the authority to create it - and they have done so.
So ... if Mr./Ms. Rightwinger rants about the "illegals" you tell him that those responsible for the problem are not in Congress. It is their local law enforcement, their local Sheriff, their State Patrol, the INS that is not enforcing the law. If Mr./Ms. Rightwinger are not reporting the presence of people that are here illegally, if they are not turning in their brother-in-law that has hired illegals, if they are closing a blind eye to the illegals their own employer has hired and refuse to rat him out, then they are complicit in a crime.
So you see, the problem with "illegal" aliens in this nation comes down to a bunch of right-wing ranters that would rather bitch about the problem than actually do anything about it. They all want somebody else to be responsible for their problems and Congresscritters are easy targets.
