Why does, after an argument or exchange of comments between two users is over, one user, finding that he was on wrong track, delete his comments?
With one user so deleting his comments, the comments of other user remain. The reader who has not read the comments earlier (that is, when the comments of both sides were present on the site) finds the remaining comments unmeaning. He is simply at a loss what the remaining comments mean. He has no clue that some beads of the actual string which once consisted a complete whole with all the comments being present are missing and, that is why, the remaining beads do not make a sense.
Is it not advisable that a user be restrained from deleting his comment(s), unless the other user also deltes his comment(s)?
