I certainly agree that a fact simply is, noting your lack of belief, however communication is only possible through description so I suspect some somantics here. My point was that within an arguement, opinions can be extrapolated from known facts to suggest unkown/unproven facts, if only so to the individuals involved. Essentially this is that basis of any argument - to exchange ideas/possibilities etc to reach the ultimate goal of determining what is a fact.

Though, as you say, many discussions and arguments, especially in a casual scenario, are taken as exercises in 'winning' rather than with the aforementioned aim. I agree this is frustrating and understand your stance.

Re respect. If you respect a person (your approach being much the same as my own), does that not preculde that you respect what they say?, at least in most instances, even if they are mistaken or incorrect? Though I think there may be two points here, one re emotional beliefs & one re fact-based beliefs. The latter being more what I've been refering to. Emotional beliefs are much closer to pure opinion than facts.
