This from an answer written by a mod a few days ago:
Even comments should be used only for asking clarifications and suggest corrections on posts (questions and answers) and many comments become obsolete when they serve their purpose. If users want to discuss any topic, they may discuss in chat rooms.
And this is a comment which did not add anything useful to the post and it's clearly attacking an Indian author for his views:
Whatever the answer to this question is. I recommend every sincere seeker of Hinduism not to read Devdatt Pattnaik or see his videos. Its nonsense to say the least. He is highly influenced by western indologists like Wendy Doniger. There is a video on youtube exposing Pattnaik.

I flagged the above comment with the following reason.
This comment doesn't add any value to this post. It's only purpose is to denigrate a scholar whose views the user don't agree with. This is exactly how personal attacks start in comments.

Why was my flag declined? What is the official policy with regard to comments like the above? Should we or should we not flag such comments?
