First of all I would like to point out that I am not trying to debate. I just like to learn a rule togather with it’s reason. Because I hate to memorize things . If I can use the why of a rule it sticks to my mind much more rapidly than if I just try to memorize it.
It is ofcourse impossible to dig into the historical facts about the whys of every rule in Russian grammar. But I try to figure out the most I can.
Yes I understand your examples. Thank you.
