You don't perceive the "religious right" as wanting limited government? I'm a Constitutional conservative and I know many Christians along with my self who have been longing for the days of hearing, “Government isn't the solution, it's the problem”, (Reagan, 1980 campaign). Maybe I misunderstood your post.
That's why I said "many" in the "religious right". There are a number of people, some of them right here on FR, who, although conservative on what many call "social issues", are definitely not for limited government if government intervention will advance their social, and sometimes religious, goals. There are, of course, many "social conservatives" who also understand, and believe in, limited government. I will put you down as one of the latter. --------------------------------------------------------------------------------
