Chill people.. Honest opinions or not, it is just represent the opinion of a person. no right or wrong and like it or not, everyone is entitled to their own opinions.

Someone may think highly of a certain dep, others may not. it could be many factors like unpleasant working rs with certain people in the dep.

As long as you dont go posting things that could identify a person causing reputation damages and having no supporting evidence on what you post, i dont think people are so free to hunt you down.
