Public Agenda, a non-profit public opinion research organization, has released the results of a new survey and finds that Americans are increasingly curmudgeonly, stubborn old mules who won’t compromise on anything. Well, not anything, but anything that seems closely tied to religious faith. Respondents’ support for compromise on “issues that involve religious principles” (survey definition restricted to abortion, same-sex marriage and teaching evolution in schools) has dropped dramatically since 2000, most notably among respondents who attended a religious service at least once a week.
