I can understand what you're saying here; and to a large degree identify with some of your frustration:
Although I myself long believed Knox and Sollecito were innocent (and am still willing to entertain this at least, and do not preclude their innocence in my doubting and questioning) , had much respect for the work of Hendry and Fisher, and for the excellent powers of logic displayed on JREF; and was annoyed and angered at the "trashing " of Knox by the media, by PMFers, and by Mignini at least in part -------
--even so, I began to sense rather early on that there was something wrong with the portrayal of Mignini, Massei, et al as thoroughly in the wrong, thoroughly immersed in anti-Americanism and anti-feminism, wholly incompetent, biased, prejudiced, corrupt, morally bankrupt, irrational in their thinking, illogical, blind to reason, given to an Italian medieval mania and folly, etc.
In the end, this is what brought me round to taking an objective look at all the facts (while maintaining my distaste for those who go overboard in the "trashing" the 2 defendants.). And on the eve of Hellmann's overturning, I had predicted that his rulings would not be upheld, while many more "logical" posters had hooted at this. So I believe I was less prejudicial and therefore could prophesy correctly how the court would rule.
