Melvin,
I think I understand oral traditions completely. No need to tell me what or what I don't understand. Its a matter of opinion as to just how accurate they are and what a more scientific approach might tell us.
So, forget my party game example and recall that here in Texas, just recently we have had several men released from prison based on DNA. They were originally convicted via "eyewitness account" but DNA later proved that they couldn't have possible raped or killed their victims.
Those eyewitness obviously were wrong from the very get go, perhaps because of some bias or another, not too unlike (or worse) than the bias shown here by DM to not believe the MCC history, or TePaul, et al biased to believe it. Both are human nature, which we all know if fallible and basically unchanged through history.
Short version: While I appreciate oral histories, I think its wise to use other avenues when they become available to corroborate.
