Minor point, but aren't people who believe Knox and Sollecito innocent at least as much of a self-selected group as those who think them guilty? What's to say it's not you whose eyes are too blinded by confirmation bias and group-think to see the truth?
I'm sure we are a self-selecting group, almost certainly an irregular mixture of anti-authoritarians, irrational sympathisers with a pretty girl in trouble, and rational and scientific thinkers capable of analyzing a complex problem.
As to whether we're blinded by bias and group-think, I'm not sure that's not the case in the same kind of way that I'm not sure that I am not Descartes being deceived by an evil demon into thinking that I'm an Australian in 2011. For that matter I'm not sure I am not in the Matrix.
However as I may have said earlier I originally entered into this discussion because I noticed that the pro-guilt arguments being put forward were simply irrational. At that point I had no previous biases whatsoever with regard to Amanda Knox, Raffaele Sollecito, Rudy Guede, Meredith Kercher, Giuliano Mignini or any of the other members of the cast we all now know. I just recognised that the
forms of the arguments being put forward by one side of the debate were consistently fallacious, and in large part they still are.
That's not a matter of opinion reasonable people can differ about. Fallacious arguments are fallacious.
Then it became manifestly clear that most of the facts the pro-guilt posters at that time were putting forward were factually false as well. That's not something reasonable people can differ about either. There were no bleach receipts, Nara never heard Meredith's death scream, Curatolo didn't see Amanda and Raffaele on the night of the murder, Meredith's wounds could have been inflicted by one person using one knife, there was no evidence of staging and no evidence of a clean-up, the bloody footprint on the bathmat wasn't any more like Sollecitos than Guede's, the luminol footprints had no evident connection to the crime at all and so on and on.
Again these aren't things that rational people can disagree about. These were core pro-guilt claims, repeated often, that turned out to be pure hogwash.
I'm 99.9...9% sure that the Massei narrative and the currently popular pro-guilt attempts at a narrative are pure garbage. That's not something I think there is any but the very remotest possibility that I could be mistaken about - false facts are false and fallacious arguments are fallacious.
I'm at least 99% sure that Amanda and Raffaele had nothing to do with the murder of Meredith Kercher, and I don't think I can possibly be mistaken that this is the rational view to take. There's some extraordinarily unlikely scenarios possible where one of the two stays at home playing on the computer while the other goes out an inexplicably commits a completely uncharacteristic murder with someone they barely know or do not know at all, then the other one inexplicably covers for them for three years, but it's only marginally more likely than alternative scenarios like "Meredith was killed by a team of three magic ninjas while Guede was on the bog" or "homeopathy works and homeopaths killed Meredith with a homeopathic solution of kitchen knife on a sugar pill hidden in a mushroom".
