A fairly old answer was recently edited to completely refute the answer's original content. I had originally rejected this edit myself, but I see that it has made it through after all.
Should this have been allowed?
One of the reasons to disapprove an edit is, (paraphrasing) because the original content is changed so much that it is basically gone completely. That's what has happened in this answer: the editor disagreed with the answer, and decided to edit it, making it reflect their own opinion instead. The right thing to do would have been to downvote the answer, and/or to add a comment explaining why it is incorrect. Editing an answer when you think it is incorrect, is something that goes against the standards of Stackexchange.
Am I the only one who feels this way? Please bear with me -- I am only trying to understand and apply SE's rules & guidelines myself.
