We point out that the guilter case is based largely on irrational and irrelevant attacks on Amanda and Raffaele's characters (ranging from the mild but factual claims about comic books, knives, casual sex and marijuana use to utterly baseless and frankly vile claims about hard drug addictions, psychopathy or sociopathy and so on) and they respond that the case for innocence must be based on an irrational desire to defend young white people and by implication racism directed at poor, misunderstood Rudy Guede.
This is despite the fact that you'll go a long, long way before you find a single racist attack on Guede based on his ethnicity in these threads. Yet you can barely swing a cat in the guilter forums without hitting someone claiming that Amanda is an emotionless, narcissistic, heroin-shooting psychopath, Raffaele is a deeply disturbed nutcase obsessed with sex murder, and that Rudy Guede was a very nice young man who had no history of violence and who would never have murdered a young woman and raped her as she died without someone like Amanda Knox leading him astray.
Needless to say, absent relevant supporting facts (like a professional diagnosis) these arguments are deeply flawed.
