How about "We do solemnly swear not to use harsh words toward one another's points of view.......(disclaimer: compact void if we disagree on any subject)"
Well maybe that won't work. lol
I saw a show on "Vendettas" (I think) about where these two families who had been fighting signed a compact not to shoot each other like they had been. They really started killing each other after the compact was signed. Maybe that's the same thing that happened on the Crevo threads.
