I just don't see the need to redefine a term. Why even suggest that a miss is not a miss?
I am sure it has been said time and time again in the thread, but I'll try stating it this way: they are not suggesting a miss is not a miss.
They are suggesting that there are ways to take away a target's hit points with a weapon without actually "hitting" with it. Yes, I can miss - the weapon never makes contact - but I can still take away hit points.
In an interpretation where hit points = meat, this is problematic. How do you take away meat without ever touching the meat? Step away from hit points = meat, and this becomes easier to interpret. Hitting the meat is one way to do damage. Hitting the meat may be the most common way to do damage. But it is not the *ONLY* way. Accept that, and the rest isn't terribly problematic.
