Well, they'll never completely go away (sadly) but Frank Rich's Sunday column does a good job of going through the culture war b.s. that's supposed to whip people into a frenzy but doesn't anymore.
In our own hard times, the former moral “majority” has been downsized to more of a minority than ever. Polling shows that nearly 60 percent of Americans agree with ending Bush restrictions on stem-cell research (a Washington Post/ABC News survey in January); that 55 percent endorse either gay civil unions or same-sex marriage (Newsweek, December 2008); and that 75 percent believe openly gay Americans should serve in the military (Post/ABC, July 2008). Even the old indecency wars have subsided.
