The man behind Arizona's new immigration law is LDS.
Fortunately, he's not the first member of the church to make a difference in immigration. Rex Lee, president of BYU and US Solicitor General, played a big role in immigration and state's rights.
In 1975, Texas passed a law similar in idiocy to the one in Arizona. Illegal immigrants in Texas could not attend public schools.
Carter's administration supported a lawsuit against Texas. Reagan became president, Rex Lee was his Solicitor General, and the Texas case reached the Supreme Court.
The Reagan administration debated which side to support. Rex Lee refused to change sides. Rex Lee, and therefore Reagan, fought against Texas.
Unfortunately, our current Supreme Court Chief Justice disagreed with Rex Lee. That doesn't give me much faith in our current Supreme Court.
However, knowing that Rex Lee, a Mormon, had compassion for the underclass gives me hope. I have a fairly good idea of where LDS leaders stand on this issue (they have considerably more compassion than most politicians in Arizona do). I hope LDS politicians will repent (if need be) and have that same compassion. I hope they will become more like Rex Lee.
