In this example
we overhastily "protected" the question, likely because one of the answers of a new user included a question about his answer being correct or not.
It is my believe that rather than blocking new users from answering by protecting a question we should help them to formulate appropriate answers either by commenting or editing. If an answer is a comment rather than an answer we should flag it for moderator attention to be deleted and transformed into a comment.
Neither a "protection" nor transforming of the answer into a comment was needed in the example above because is could be turned into a valid answer by simply removing the additional question part.
Is there any way to "unprotect" a protected question in case we feel that protection was not really justified?
