We all adore the idea that love conquers all, for instance, but we like to be reminded of it from new angles. You can never write something that everyone will love. Neither statement is true. Nonfiction often rearranges events, corrects quotes, drops people or actions so as not to confuse things, and generally cleans things up. No, if it's done in the name of clarity.
Meaning is what's important.
After a good interview, I leave with more than just words on a tape recorder. I was with that person live. I sensed body language and took in gestures. More came across than just the words, and my written interview is an attempt to get that meaning across. Anything that clouds clarity needs to be eliminated.
