I am simply saying how else do you describe the hand. The hand is for grasping things the rock is not. How to I ascribe this difference without using the word design or purpose because clearly the hand is much much more efficient at grasping things.
Sure you can use the hand for things it was not "designed" for like hand stands and walking while hand standing and if there was selection pressure your hands can evolve to be less hand like. But in doing such things you are departing from a "design."
Let me put it in a way that won't distract you. Your hand is efficient at grasping things by doing hand stands you are using it in ways that are not efficient. You are departing from the efficiency zone. There is merit in ONLY using the hammer on a nail rather than a screw driver even when the hammer was evolved with Zero actual "design" or "intent" and can one day evolve into something different.
Get it? So the same thing applies to not eating meat. By not doing so, someone is departing from the "efficiency zone." See how awkward it is to use "efficiency zone" in place of "design"?
I'd rather operate in my efficiency zone rather than push the boundaries of it just so that my progeny 1 million years later can walk on their hands. But that's just my personal take. My argument itself has no agenda other than to say that by not eating meat you are willfully departing from the efficiency zone. By being compassionate about the pig you are doing the same. And using the word "design" is just an EASIER way to express this departure from the "efficiency zone".
