What you say is entirely true, Slag, but I don't know that there is a good solution. We have all been involved at one time or another in threads in which two or more people with rigidly entrenched ideas "talk" back and forth in circles for days, seemingly without listening to the other(s). The only real thing to do, since the mods won't shut them off (and there isn't any real reason they should, under Mudcat's rules), is simply to leave.   It's a shame, really, since a number of interesting discussions have been hijacked that way.
