I'm not surprised that the BMI article was picked up by other conservative outlets, nor am I surprised that a liberal Web site characterizes conservative sources as "right-wing".
I think what gets me the angriest in the whole terminology used department is how you accurately described that web site as liberal, yet the main stream media (by this I mean ABC/CBS/CNN/MSNBC/NBC/PBS/NYT/WP/LAT/Time/Newsweek etc) NEVER use the terms liberal, leftwing, socialist, communist, etc, but always ensures to identify the right wing, conservative media outlets, web sites, blogs, etc.
So when I see right-wing media machine, etc, etc, half a dozen times my eyes glaze over and my give-a-$hit meter is pegged at about zero.
