If you want to read an excellent, crystal-clear piece on the negativity of "illegal" as in "illegal alien," see Lawrence Downes' op-ed in The New York Times today.
You don't have to agree with the people who advocate amnesty or who think there should be an open border--and I don't entirely --to appreciate what Lawrence is saying about language. He puts the word into context of what's legal or not; what other "crimes" are brushed off in our society. This may make you think beyond the matter of political correctness.
Should be required reading for those obsessed with the immigration issue, like Lou Dobbs, Bill O'Reilly or Michelle Malkin. Did I mention Lou Dobbs?
