I agree. And it mystifies me as to why so many conservatives fail to see (or admit) the broader point of Buchanan's article. After all, we are the ones who have been making this point for decades.
It wasn't too long ago that conservatives could all agree that moral decay, relativism, and various forms of "personal liberation" were a grave threat not only to the US but to Western Civilization as a whole.
Just because we're fighting a war against terrorists doesn't mean that we should suddenly cede our culture to the likes of Charles Krauthammer, in whose mind the West's greatest achievement is evidently "sexual liberation." What a freak!
Maybe because they secretly enjoy the decadence. They pay lip service to the "moral values" only to get votes, money and support from the "simpletons". In real life they are one social group with the left wing libertines.
