I don't know about context saving Rinaldi's reputation. Civilized people are respectful and polite even in the face of foolishness, insults, and bad behavior. That said, I think its unfair the Rinaldi was singaled out for criticism. Everyone can make a mistake now and then.
Per trolls, there are a lot of self-appointed troll sheriffs around here. They're the ones that need to be stifled. A good discussion is a good discussion, not trolling. Too often a "knife expert" gets his back up or someone challenges a "sacred cow", and those with bad tempers start screaming troll. The post on Strider knives is a good example of someone having fun by starting an animated discussion. If you can't handle it...don't read the post, or turn off your Dell, but don't scream troll just because someone has skewered your sacred cow.
