The distinction I see would be this: Style is how you lay out the article and make the argument. Rhetoric is more about the content of the article itself - what phrases you use, what slogans, terms, etc; how you frame certain issues. Most publications, fringe or not, have journalistic style that would, in my opinion, make them hard to distinguish. That is, if you took a Brietbart article and a Vox article on two different issues and compared the format/length/general tone and language, they wouldn't be all that different. However, I think these outlets do vary in the specific rhetoric they use, the people they rely on for comment/as sources, etc. I would therefore focus on specific terms or language rather than general style.
