Well Azizi, you have asked quite a question. I've never seen it expressed in quite that way. I've 'almost' started to type several times, but decided I wasn't ready to approach it in the multiple levels I think it requires. The more I think about it, the more important it feels.
I am fairly sure I won't approach it in all the usual ways. For one thing, as you indicate, one needs to consider the nuances between 'does' it matter? and 'should' it matter?....and why?...and to whom?...and when?

   There are as many shades of meaning in some of the questions as there are shades of 'dark'..(Once in my life I met a man who was actually black)

Before I get in over my head and end up writing a 12 page introduction...*grin*...let me ponder a bit more. (I have a major craft show in a couple of weeks, so I am not focused on Mudcat heavily)...but I'll see what I can do.
