It's no surprise whatsoever that Glenn Reynolds is blaming the CBC for teenager 'hating America'. Calling for censorship and attacking a free press (no matter where it is) because it actually reports when the American government does bad things is normal for him. It's what he does.
It's also no surprise that he's drawing on a study by the Frasier institute with what appears to be incredibly weak methodology too; that they choose not to distinguish between accurate and inaccurate reporting and just rail against "negativity" is par for the course, as they singlehandedly justify every negative stereotype about rightist tendentiousness. It's what they do.
In fact, the only thing that surprises me is how much wingers seem to get away, considering they expend so little effort.
