This was not a borderline call! The GP comment is not in keeping with the kind of discussion we're hoping for, especially not at the top of a thread—which unfortunately is where cheap negative comments often end up.

The problem isn't primarily with the comment, and in that sense conradludgate did nothing wrong. The problem is the upvotes. If it weren't for those, such comments wouldn't rise to the top and choke out more interesting conversation. But they routinely do, and that's one of the biggest problems we have here.
