The United States seems to be divided on a number of religious, political, and cultural issues and values. We might characterize the opposing sides using terms like "liberal vs. conservative," "modern vs. traditional," or "progressive vs. old-school"; some of the most bitter debates across these lines include abortion, gay marriage, and gun control. As you know, debates over issues like these can be intense, bitter, and even violent: Adherents of one position may view their opponents with utter contempt, demonize them, and dismiss their arguments. How deep is this fault line in U.S. society? How do I input this into SPSS?
