If a story happened to me, and I want to get true opinions, I may post from the viewpoint of the other party, in order to be unbiased.
Or if someone told me one-sidedly a story of a disagreement, I will pose as that person to bring out how it sounded to me.(I may also change a few details.)
Similarly, I sometimes will answer questions in a purposely contrary fashion so I can create a clearer divide in the opinions on the issue.
If the story is ridiculous, it may be the way I see the story, or may not be completely true.
