On the guitar mailing list I've been on forever, barbecue is kinda their lembas. As in...if it ever gets really quiet, someone will post something like "vinegar ain't no part of real barbecue".
And everything goes insane for a little while. It's kinda fascinating, being as how I don't have a dog in the fight. I'd be happy to eat any and all varieties.
At least we don't put mustard in it.
You know "he needed killin'" is still a valid defense in the South.
