Regardless
Two of those defenders—whose opinions and approach I greatly respect—are Josh Bernoff, author of Writing Without Bullshit, and Peter Wehner, a columnist for the New York Times. Since they can say it much better than I can, I simply give you these two links, and strongly recommend you read them:
Bernoff: The Truth Foundation
Wehner: Moderate Is Not a Dirty Word (This is the title of the print edition of the opinion in the NYT; different than the online edition for some reason.)
