I don't give the NFL credit for much when it comes to rules, but they did make head hits on QBs black and white, no room for debate. The NHL needs to do the same and get rid of the language that allows for this discussion.
"My views aren't reflected in the realities of this sport. The league needs to change to satisfy my wants."
The "language that allows for this discussion" is not some poorly written oversight. It's by design to allow for the ambiguity of the situation and to keep player safety rules from changing the game.
A. A player leaving it too late to cutback and getting hit by an already committed player is nothing like the inherent vulnerability of a QB standing in the pocket. What your advocating for would be more like a rule that if the QB sees the rush coming he can spin his back to them and become ineligible to be hit and the rush must do everything possible to avoid the collision, throwing themselves out of the play and allowing the QB to complete the pass.
B. The last thing the league needs is more americanization of it's rules. Next thing we know we'll have players trying to draw the charge defensively and deliberately losing control of the puck and shooting it over the glass when they feel contact to draw a penalty.
