There are different ways readers can respond, or react for that matter, to articles. Anger is one reaction; the article is so stirring that one is thrown into a negative emotional reaction.
Articles that deal with issues that polarize can always get a rise from some people. These can be basically useless articles if anger is the main response.
However, for the unconverted on some issue, these kinds of articles are ‘dangerous’ in that they have the power to persuade.
Factual articles outlining the issues and going in depth are better, as they help someone find where they stand on an issue, rather than persuade or coerce.
There are also articles that make one think, but these tend to make one think for a moment, and then, that’s that. No further action and thinking required–but, what if, in that moment of thought, a writer drew someone towards a conclusion?
This is when articles that make one think are useful or put someone on the wrong track. In the end, they can have the power to persuade.
The best articles it seems are those that inspire someone, be that personally, or to action. Then, one may ask: inspire to what?
Writers can be ‘dangerous’ people.
