"Here I speak only of myself, of course. I have no idea what anyone else thinks, although others here are never afraid to make such assumptions. "
Just once, Blue, I'd like to see you take a leap into positing a viewpoint, an opinion, an assumption of your own . . without worrying about being right, or not covering every possible situation. You DO make sassumptions . . we all do. They may not always be right, but if we don't assume some things, it would be hard to function in life. When you are driving, I assume that you assume that other people will abide by the convention of traffic lights. But, it is certainly possible that someone might not. So, to avoid making a potentially erroneous assumption, do you approach each intersection with trepidation, unsure in the knowledge that a green light means you are safe to keep driving through the intersection, and that crossing traffic will stop for red? Sometimes that is not an accurate assumption, but I think you and most of us make the sassumption in order to function adequately.
Or, when you enter a store, do you not assume a degree of safety? Or, do you not wish to make that assumption, considering the possibility that any of a number of fellow shoppers could produce an AK 47 from beneath their coats and mow you down. There are parts of the globe where an assumption of safety might not be realistic. But here, in U.S., or in Europe, etc. if you did not make the assumption of safety (albeit, there is no guarantee) how could you, or I, function in society?
So, if we make assumptions about some things, why are other assumptions considered (by you) folly? Courage Blue, make and express some assumptions. I might not agree with your assumptions, but it would be refreshing and welcome to me to read them.
