I've only read Riehl occasionally, but that opening paragraph causes me to lump him in with the likes of Andrew Sullivan, Ann Coulter, and the harpies that post at Huffington Post and Firedoglake. I didn't read the piece farther than the first paragraph.
To be fair - Dan did NOT write the opening paragraph. Granted, it was over the top and a bit too much, the writer at C4P drafted the intro paragraph - Dan’s actual comments were fair, reasonable and probably much more to your desire for “fair & balanced” commentary.
