In it he attempts to conflate anti-illegal alien measures with the ethnic cleansing in Kosovo.
Card invokes a commonly used disingenuous argument: that those of us who wish to get illegal aliens out of the US are anti-immigrant. In fact, every single shibboleth he raises in the article comes from the left side of the aisle--from the people who think that US citizenship is a civil right regardless of where you're born.
Card's essay maximizes the benefits of having 12,000,000 illegal aliens in the US without counting any of the costs. It makes no distinction between the actions of legal immigrants and illegal aliens.
Just to give an example, illegal aliens generally don't pay taxes and do heavily use government services for the poor; for the most part many of those services are denied to legal immigrants for the first several years of their stay here. California, for example--despite having the highest total tax rate in the nation--is struggling to find ways to pay for the enormous drain on its coffers that the illegal alien population represents.
Illegals don't want to integrate; they're here to make money and send it to Mexico. There was a big flap in the media not long ago, over a woman who had been in the US illegally for twelve years and never bothered to learn any English at all. She had been in the US illegally, was found out after 9/11, and deported. Then she came back, got an illegal forged Social Security card, and was working at O'Hare Airport until she was found out.
Card's article treats these illegal aliens as if they are here to become Americans, and--well, hell, he just gets it all wrong, is all. That's all I can say about it. His article is based on a romantic notion that has nothing to do with reality.
It's a shame, really, that I don't have the energy or the desire to deal with his article in detail. But it's enormous and it's all wrong.
