Do you think the player in the winning position should be given the win if he or she is sharp during the opening and middle game but not sharp during the endgame?
That's very true. I've gotten many wins because my opponent's play dropped significantly in the endgame.
I am not talking about being a pawn down, or two, with some pratical but remote chances to survive.
I am talking about being LOST. King vs King and Rook. That kind of thing. Or King and Pawn, vs King, and you cannot stop the pawn from promoting, because your king is too far away.
You should reckognize that you have played so badly that you don't have the right to waste your opponent's time any more.
You should recognise that players can get stalemates in very lost positions, and often do. I have gotten many from opponents getting too complacent and forgetting to double check if their move is going to award a stalemate. Why should anyone resign with that possibility when stalemate is a legal outcome in chess?

Do you dispute the legality of the Stalemate rule? I can only see you do to not think it's fair and right to allow every opponent to fight for a legal/allowed rule/outcome of chess.
