Where is the gunner? How about the daddy's boy/girl, who is only in law school because they don't know what to do with their life and their father is a big alum.
Even though "gunner" is often used to describe the blowhard who always talks just to "enlighten" the rest of the class as to their viewpoint, it also has come to mean "Person who is speaks up often" even when they are efforting only to express their view to have it challenged and corrected/refined, or because they feel the knowledge they have aids the discussion.
In the end, if students find it more annoying to have students speak up consistently instead of listening to the professor, I think that is evidence of their lack of imagination. Imagination and creativity is important for lawyers. So is voicing your viewpoint in front ofyour peers.
Stop attacking Gunners and start attacking the ideas they constantly share. If you can debate the merits of their words, instead of arguing agains the necessity of their expression, you'll shut up Gunners quicker than ridicule and whispers-behind-their-backs.
In other words, stop gossiping about Gunners and riducling them and instead attack their ideas as irrelevant to the discussion or misguided.
