Great General Winfield Scott! I'm a little surprised at the number of people willing to ban an entire type of subject. I understand the difficulties that come along with 'versus' threads, and I understand that it does mean more work for the moderator, but I think that just comes along with the job.
Is this forum really so puerile and uncivil as to need certain toys removed from the sandbox so that the kids play nice? I don't think so. I've seen worse forums. I think we can handle a few delinquents without parental guidance.
I say don't ban the threads.
