He didn't say the OP was stupid, just the comparison. I would say a variation of that, but might actually say 'stupid', depending on how amiable the group/person is, and how well I could inflect my voice to my funny instead of mean.
That's a poor example then. "Calling names" generally refers to attacking the person/people, not ideas/things. I saw nothing uncivil about the 'stupid' post, unless you chose to read it in an iflammatory tone of voice.
