Doug Karr, product manager for a "permission-based email service provider" (permission spam?) lays down three interesting rules for understanding differences of race, religion, politics, sex and bigotry: 1. He will never understand others; so he tries to respect things that he doesn't understand. 2. Everyone is different and unique. and 3. Double standards are part of life; so accept it. While they sound very reasonable at first glance, I strongly disagree with all three of them for very fundamental reasons.
