Agree or disagree?
I recently reviewed something on here, and I noticed that none of the options really fit. But the edit was so insignificant that it seemed to me that it wasn't much of an edit at all. Plus, it's more like an insertion of another person's opinion in the original. It's not really a "radical change", but it's a change to the extent that it changed the view or presuppositions of the author on the topic.
Nevertheless, I just gave a Custom reason for rejecting the edit.
