New Chapter, I hope I can explain what I mean. Sometimes it's not so easy for me to clearly express my thoughts. What I mean is taking ourselves, as individuals too serious, or rather not to do so. I differentiate between that and taking issues and a cause serious. Because I don't take myself as an individual that serious I can deal with being wrong and respect others and what they think and am willing and open to consider what they think. But it doesn't mean that I don't take issues serious that need to be addressed, it doesn't mean that I'm not watchful. Quite contrary. I differentiate between myself and principles/issues. Lets take the hotheads in the middle east as an example. They are crazily serious about their views (fundamental Christians aren't that different). Just because I don't take myself as a person and my views overly serious it doesn't mean that I wouldn't stand up against them, I would, I do. We all have the freedom and right to have our own opinion and views, but we have the duty to grant others the same freedom. When others don't abide by that it's a matter of principle and that needs to be addressed and taken care of. It's an issue that needs to be taken serious, as you said and I fully agree with that. I hope I'm making sense. You could say one is about taking personal offense and the other about justice and fairness. When things become a matter of fairness and justice it's important to do something about it.
Ideally we should all be able to sit down and listen to each other and say: "Hey, I don't feel or think the same way, but who knows, you may be on to something. Either way, I respect your view and how you feel." And we should confront those who are unwilling to do that. But that's another story, usually those unwilling have a problem with fairness.
Btw, I'm not sour.
