What outsiders? I see the usual people fighting with the people they usually fight with.
And why not Rome is burning and this beats fiddling.
You're right, the same crowd always fights the same crowd, and if a new thread is posted, those same people show up to fight those they feel are dissing them. So the question is, is it the topic, or the posters who want to trash each other? Kind of looks like the later, keep the home fires burning and all that.
