Apparently, since religious people started favoring immigration.
Actually, to be fair, when you go back through Dobbs's writing on the subject of religion, he seems to take a fairly consistent position that there ought to be a fairly strong wall between church and state. You also notice one, um, peculiar element of his opposition to the role of religion in politics: it seems to have no basis in specifics beyond the tendency of religious groups to support immigration. That commentary above is from 5/9/07. On 9/28/06, he wrote a long, stirring piece about the unacceptability of politically active churches, but the only examples of impropriety he saw fit to mention were friendly overtures toward foreigners generally and Mexicans in particular:
The mixture of religion and politics is on public display throughout the country. The Mormon Church rolled out the red carpet for Mexican President Vicente Fox, embraces illegal immigrants in the state of Utah and helped pro-amnesty incumbent Congressman Chris Cannon with a get out the vote campaign.No mention of stem cell research, or Terri Schiavo, or young-earth creationism in the classroom. The real problem is being too friendly with the president of Mexico.
Apparently nobody in the federal government is too concerned that the Catholic Church has repeatedly lobbied on behalf of millions of illegal aliens and their supporters for wholesale amnesty and open borders. Until the Supreme Court ordered him to, the head of the Los Angeles Archdiocese, Cardinal Roger Mahoney, didn't think he should cooperate with the law when it came to divulging information on priests accused of pedophilia, and he believes it is entirely correct to encourage his parishioners to civil disobedience in the case of legislation that secures our borders and punishes those who cross them illegally.
