I do think it's idealistic (not naive really) in that I believe most pro-acquittal commentators (and certainly most who are not emotionally attached by virtue of being close to Knox or Sollecito - which is why I'm not keen on terms such as "Knox supporters") have approached this case in a logical and open-minded way, whereas most pro-guilt commentators are guilty of emotional prejudice, reinforced by confirmation bias, cherry-picking and rationalisation to fit their prior thesis.
So - as we are indeed seeing right now - most pro-guilt commentators are assessing the SC verdicts by searching for rationalisations that fit their preconceived prejudices. Either the SC has become corrupted (by money or political fixes), or the SC judges are plain incompetent. Either way, nothing can be allowed to shake their central belief that Knox and Sollecito really, factually, did participate in the murder. If they can make themselves believe that this is an OJ-style scenario of killers "getting away with it", particularly if they can transfer some of the blame for their acquittal onto the evil forces that corrupted the SC, then that will preserve their mental and emotional equilibrium.
So regarding the problems in the investigation and the various trials, I am very confident that the stock pro-guilt reaction will be that the investigation was more than adequate and competent, that the Massei and Nencini trials were essentially perfect, that Hellmann was either corrupted or incompetent (with the tasty side-excuse that Conti/Vecchiotti were in league with the defence to ensure the fix was in...), and that the final SC ruling was the product of corruption, bribery, incompetence or some sort of hidden agenda.
It's worth bearing in mind at all times that the likes of you, me and many others here approached this case with totally open minds, and we went where the evidence (and lack of evidence) took us. We were also open at all times to new evidence, and for that new evidence to alter our conclusions if appropriate. I (and, I imagine you) don't care at an emotional, personal level whether or not Knox and/or Sollecito participated in the murder. If I thought the evidence supported a conclusion of their participation, then that's what I would have readily concluded. And I would have readily switched to that conclusion at any time if new (reliable) evidence showing their participation had come to light.
But I (and you and others) thought that the evidence not only didn't support a conclusion of Knox's/Sollecito's particpation, it also even tended to support their factual innocence. I therefore concluded that neither Knox nor Sollecito should justly be convicted of participation in the murder, and I also concluded that they were almost certainly totally innocent.
I don't think, from reading their arguments and views, that most pro-guilt commentators have approached the case in that way. I think they've quickly reached a presumption of guilt, then have constantly searched for evidence to support that belief while simultaneously minimising, rationalising or ignoring anything that points away from that belief. Which is a classic definition of poor thinking, of the sort you often see from religious zealots or Moon-landing-hoaxers.
