Here is an excellent column from Hugh Hewitt at The Washington Examiner on standards of public discourse. We especially liked this part:
There is one standard for all commentary, and it ought to apply to Palin and Ms. Fluke, to President Obama and President Bush, to Justice Thomas and to Justice Kagan.
So credit nothing of a condemnation from anyone who has not first articulated his or her standard, preferably backed up with a reference to the rebukes they have handed out to themselves and their own team, and only if that standard condemns all of the profane, the vulgar and the bigoted.
and also the end:
If the country abandons the right of religious people to keep their own creeds, it can hardly complain when no creed at all exists to restrain conduct or prompt apologies when they are indeed deserved.
As they say, read the whole thing.
