My grandmother winces at me holding a rat or guinea pig, so yes, I'm sure she'd wince at witnessing a declawing, or any other surgical procedure. I honestly doubt that declawing will ever be completely banned, as there is no hint that even docking will be banned in the near, or far, future.
As far for it not justifying, it may not for you, but it does for her. And if you carefully check my posts above, you would have seen that it said that I would not have done it if it was me. It is not for pleasure, either, as I have told you multiple times now.
Also, I did not say it was "only" phalanges. I was correcting you saying that it was part of a bone. It is not part, it is all of one the bones in a paw, the distal phalange in all digits. It would seem that you, not myself, don't understand what declawing truly is, and how it is performed. I have seen declawing done, I know how it is.
