Concealed Claims

So in Chapter 9 I read about Concealed Claims which is where one uses slanter in order to convince someone of their claim without using any argument whatsoever. Slater is defined by "any literary device that attempts to convince by using words that conceal a dubious claim". There are two types of slanter; loader questions and "making it sound nasty or nice". Now this is very interesting to read because Ive read slanter all the time, especially in news articles, but I could never clearly understand the what exactly was "wrong" with what I was reading. For example in the newspaper I read articles by Tim Kawakami, a journalist, who is always skewing the article to reflect his personal opinion without really giving any credence or argument for that opinion. All the time he asks loaded questions (why aren't you winning? etc...) to sports teams and then proceeds to shift the article towards that loaded questions response, which more often than not results in a negative article.
