Thanks for the response Dr.M. I wish you had just quoted some pertinent snippets from your article so we could all see what JV actually said. Especially if it's something older or from behind a paywall, many posters may not have read it, so it might have been enlightening.
I think the easiest thing might have been to just say, in some kind of non-confrontational way, 'I remember it this way instead.' Here are these quotes/source, ask the other person to link their source, and just leave it to the individual readers to decide who made a better case. It may be that the other person honestly mis-remembered or misinterpreted what they read. It may be that they picked it up secondhand and were misinformed. Or it may be that different things were said at different times/different context, changed his tune, etc. If we had both sources, we could decide for ourselves. And if the person is truly spinning/trolling/lying, that will likely show up.
It sounds like you had some mod intervention before you got to post your source. Maybe in the future, especially with the posters where you know there's a good chance of going off into bickering back and forth - instead go straight to quoting your own evidence so if an argument does ensue, it remains content-centered? That might be more likely to convince readers of the solidity of your position. Once a couple guys start accusing each other of trolling, it kinda goes off the rails. Don't use the word "troll," just show the holes in the other guys argument, and leave it to the reader to decide who made a more substantive case.
Anyway, just wanted to say thanks for the polite and thoughtful discussion in this thread. It can't be easy to sit around and read/talk to folks about your own posting habits and what they like or don't like, but kudos for being open to the conversation. It has not gone unnoticed, I'm sure by many folks.
