I think in one of the videos from the XMRV workshop last September Coffin said he thinks we can be pretty confident about XMRV playing a role in ME/CFS, only that he's a bit worried about how easily PCR can lead to false positives. Now he said it should be left behind.
I don't understand what's going on but i don't like it and it's even pretty scary. This should be about science and the truth and besides that it's about something as irrelevant

as the health of the human race and what we mostly see is people fighting each other in such a way that at least to me it seems as if they basically care about their own career, their own interest. * that.
If i look at the Coffin video it feels like a gathering of Mafia capos where everybody is making plans how to kill the others and get control of the whole thing.
I don't want that sort of mentality deciding my fate.
If Coffin turns out to be wrong, he certainly has done a lot of damage to his reputation. Would he take such a risk? I don't know. But even though i'm no scientist i think there's a lot that his hypothesis can't explain. What about the sequences Lo and Alter have found, for example? Can they be explained by recombination of preXMRV1 and preXMRV2?
Many people say that XMRV is losing interest of researchers, but just look at all the XMRV-related events... University of Alberta, NYAS, this workshop... all in a couple of weeks. It does not look dead at all at this moment.
