I have no problem exchanging points of view as it might enrich my own, but as soon as it becomes negative instead of positive feedback, I will appologize and back away, as I assume that I've somehow violated your borders. If you in turn violate mine, there's no room left for curiosity. Respecting each others space is far more condusive (sp?) than make people back up into a defensive little corner. If you do by accident feel you've violated them and a sorry can rectify that, you can continue your conversation on neutral territory.
