According to the startling results of a survey released last week by the Public Religion Research Institute, 57 percent of white evangelicals live in homes where someone owns a gun (compared, for example, with 31 percent of Catholics.) And more startling, even after 20  first-graders were slaughtered in Connecticut at the hands of a madman with an assault rifle, 59 percent of white evangelicals continue to oppose tighter restrictions on gun laws.
