I received three review reports for a work, and while two gave good recommendations with minor reviews suggested, the third reviewer saw nothing good in the work right from the topic. The comment given were all negative and some were really insulting. I was not expecting all nice reports, but putting his/her views across without being all arrogant about it would have been great. Now I have to submit a response to all reviewers comment and I am finding it hard to respond to the comments of this particular reviewer.
While trying to keep calm and answer every questions and comment of a reviewer, how do you respond to comments that appears to attack the person rather than the work itself?
