As many have stated before, it is reasonable that people disagree.
It is the reaction to disagreement that is puzzling.

I suspect it is sometimes the nature of the topic. Othertimes it may be the tone the disagreement takes, rather than the nature of the discussion(from either or both sides).

It is interesting to see people say they are "walking away from a pointless disagreement,when they are just taking time to recharge and return to it.

People seem to react differently to different situations. I suspect that "road rage" is a good example of normally reasonable people acting unreasonably, and often out or charactor as to other aspects of their lives.

I often wonder:
If somewhat reasonable and logical people on Mudcat (a kind of mild natured, middle aged, and music loving lot)can't come to some type of agreement on the Israel-Palistinian issue, (without significant emotion and discord), what hope can those have who are directly and deeply involved have in reaching an agreement (outside of being forced into one)?
