The article gives insight to the opinion of the professor, but doesn't offer linguistic analysis of the speech used. Maybe he's right in his analysis concerning the concept of framing, however, I agree with the ideas expressed by the Republican speaker's frames. But I see it as a good thing. And I'm part of the public. The professor assigns opiniated judgement to his "findings."
The professor doesn't agree. Rather than simply presenting his findings, he politicises them, rendering them void. He becomes subjective by mentioning the public, as if everyone knows what the hell he's talking about. And if you don't, well then leave me alone with my bad science.
The article alone amounts to nothing more than opinion, and is not a scientific linguistic analysis without diagramed formulas breaking down the paragraphs and individual sentances. All legitimate academic proof of a theory rests on this alone, whether it's proven true or not over time.
