Opinion marks a content type that argues a position on a current or contested topic. Unlike a news item or a guide, the piece does not offer a neutral overview, it presents a judgment from the outset.
A stance, not a neutral account
The author takes a recognizable position on a topic and argues for it. Facts serve as the basis, but interpretation and judgment carry the piece, not a plain account of events.
The type fits topics with more than one defensible view, where a sharpened position moves a discussion forward. A reader looking for a neutral account without judgment finds it in news or a guide instead, both built to avoid taking a side on the matter.
