I am reading an article that is highly ideological, and I am supposed to write a critique of it. I say that it is ideological not because it tries to enforce an opinion, but rather because I can tell from the authors' use of language and dialect what their opinions are (i.e. they use words that are common among certain subcultures and would never be used by members of different cultural/ideological groups). What would should I use to describe writing that is so strongly dialect-based?
Example sentence: "The author's writing was highly ____, I could easily tell what their political, religious, and social views were by analyzing their word choices and dialect."
