A person (in most cases a supporter of the Religious Right) who intentionally ignores the 1st amendment to advanced a certain religious groups moral agenda over another. Ignore the fact the 1st amendment clearly states that the U.S. can not endorse religion.
Clearly some one who cherry-picks the Constitution without any respect for the constitution as a whole.
These type of people tend to support or smpythise with Social Authoritarian(a.k.a. Radical Social Conservatives)
People who can't fully be trust with the reigns of Government.
