Perhaps the Mods should just create two Dylan threads. One for those who think MR is involved and one for those who don't think he's involved. It sure seems like things would be much more harmonious that way. That way those who don't think he's involved can talk and brainstorm on other theories and those who do think he's involved can brainstorm in that direction. Just a thought...
FWIW, I proposed this very idea many, many, many threads ago as I, too, felt that it would be more constructive to have individual threads based on which theory one wanted to pursue. I received a response from the higher powers that be that this was not possible.
