These days, the three bloggers most likely to produce a 'what he said' reaction for me are perennial favorite The Carpetbagger, Digby (although I sometimes also violently disagree), and Robert Waldmann (with two N's!).
See, for example, Robert's reaction today to the NYT's latest piece of dangerous fluff, an article fuller of Republican spin than facts. Bait and Switch at the New York Times exactly captures my reactions when reading this thing over breakfast this morning.
That said, I am not endorsing the following statement, in an earlier posting, at least not without further testing:
This brings me to the best established hypothesis in the social sciences. The Romans had a theory that they won wars because the gods were on their side. They felt that so long as they performed traditional Pagan rituals they were fine. After converting Constantine as Pontifex Maximus ordered Romans to keep up the Pagan rituals then moved to Constantinople. For centuries Romans ruled and performed these rituals. Theodosius banned them from performing the traditional rites. Rome was sacked within 30 years. Sure it was just a coincidence suuuuuure.
