I could propose a complement approach: when inserting comments to the page, pg could automatically prefix all paragraphs with "I think that..."
That would remind people of the true nature of their words and help them remember that the commenter is just stating what he thinks is right and not an attack against the reader's personal state of world. That where I think all useless arguments start from. There's a difference in reading "Water is dry" vs "I think that water is dry". I try to implicitly "hear" that prefix myself each time I'm listening to someone talking.
