A POINT OF VIEW
The reaction to another's point of view by someone with a different point of view is not due to the opinion held by the other, but due to the opinion held by the person reacting. Anger is ones own, as are all ones emotions, and cannot nor should not be blamed on the words expressed by another. To say something which is offensive to another, though being considered disrespectful, is not the cause of the 'disturbed' response from the recipient, who is responsible for the control of all the emotions he possesses, thus is offended due to his own shortcomings and not by the 'offensive' words of the other.
How do you offend a person who smiles at you each time you abuse them with vocal obscenities? Your anger wears out, and it is seldom that similar abuse is offered to the unaffected 'victim' thereafter, for anger and abuse requires a like response to satisfy it's hunger, which more often than not is caused by 'pent up' emotions that have not been freed from the mind.
We are all subject to a host of emotions and often it is not an argument we seek but an ear to listen. Listening is far more difficult to do than to offer opinion which most of us are apt to do, for do we not all feel that we understand and know all about the plight of another. All who have raised children would have experienced the learning process whereby advice given without request is seldom acted upon, though often is not forgotten by the recipient, (stored for later use perhaps).
If we do not listen we will learn very little, for despite the fact that we often think we know what we really don't know, we are only satisfying our own egos in giving non-requested advice. This does not restrict 'opinion' very much, but then opinion is, simply an expression of perspective in the absence of facts, which is what all this is.
