Poor Michael Newdow. Seems this is one atheist the courts don't take seriously.
So far, he's lost challenges to the words, "one nation under God" in the Pledge of Allegiance, to the words "In God We Trust" on our coins, and an injunction against SC Chief Justice John Roberts from prompting Pres. Obama to say "so help me God" at the end of his oath of office. (Those four words aren't required by the Constitution, but have been added by every president since George Washington first spoke them in 1787.)
Now SCOTUS has refused to hear his latest appeal in re Newdow v. Roberts (10-757). Why? 2009 is moot, and he doesn't have standing for 2013 or 2017. In fact, it's a common refrain he's heard in most decisions — he simply didn't have legitimate grounds to file or be part of the suits.
What makes his case even more pathetic is that he's won awards from humanist associations for his windmill-tilting. "Wonderful thing, you're doing, old chap, to advance the secularist cause — wasting all your money on frivolous legal action." And he has actually made a religion out of science: the First Atheist Church of Truth and Science (FACTS).
Sometimes attempting parody is little better than lily-gilding.
