You're talking about the Bible Belt here. Language like that doesn't win friends for Gingrich.
I had a long talk today with a local Republican official in which I said that I can live with Gingrich, but I'm seriously concerned that a Gingrich nomination will enable an anti-Christian secular spirit in the Republican Party that acts as if it wants to turn the GOP into a European-style conservative party which favors free markets, law enforcement, the military, and nationalist issues, but opposes a role for religion in the public square.
I do not believe Newt Gingrich wants a secular conservative future for America. In fact, I think Newt Gingrich may want a new crusade in favor of Western Judeo-Christian civilization against Islamofascist tyranny. I like many things that Gingrich stands for, and while I voted for Santorum, I believe that a conservative Christian can vote for Newt Gingrich in good conscience if that person believes Gingrich is the best candidate to defeat President Obama.
However, quite a few of Gingrich's supporters are harming his case. People who say things like what you said only antagonize the Christian conservative movement within the Republican Party.
I believe Gingrich knows better than to do that. I wish his supporters did as well.
