"Don't they mean "Left-wing extremists"?My initial reaction as well.
Political extremism is not an ambidextrous quality, as percieved by the "lame-stream" media. It only can exist right of center.
The media don't see them as extreme because they are on the same page. No one consuders themself an extremeist, so it is difficult to label those with the same views extremist.
Mainstream Media - America's #1 domestic enemy.
