Thank you, Mr. Nikulin, for writing this long message. I am totally with
you in many regards, and have been following this thread for some time,
mostly wondering and finding myself unable to put into words, what was
bugging me with it. It is quite a challenge to see it the way you (and
i) do, while still being friendly and helpful to the OP. but you managed
that, and i admire the way, you are doing it. Very nice and fine
distinctions like (i'll give one example only: )

Just saying: I do very much appreciate your post. Thank you for that.
