I have read the guidelines but they don't cover this situation. There doesn't seem to be a way for me to respond (or, especially, not respond) other than like I did. How should I, assuming the following:

-- The literal part of the comment was misinformation.

-- The subtext of the message was flamebait, implying that people are fat simply because they cram too much food down their throats.

-- No response would have just left the false information hanging thus validating the idea. Therefore no response was not a useful option. (Think anti-vaxers. Don't want to leave misinformation alone because it propagates.)

-- A response that talked to the points made in the comment would have validated both the text and subtext even further.

My response pointing out I was aware of the misinformation and the subtext to let the poster know I wasn't going to validate it nor accept it seemed to be the appropriate solution.

What would have been the proper response that would nullify both the misinformation presented in the comment AS WELL AS the subtext?
