There was a tendency at one point to use the McCann's lack of previous wrongdoing and the fact that they were doctors to suggest that they were unlikely to be involved. I think posts such as the one you mention were demonstrating that people's pasts and/or their jobs are not 'proof' of innocence. To some extent CB's past is being used by some as if it were 'proof' of guilt.
Just as the McCanns became 'poor', 'suffering' and 'doctors' to emphasise a message, so CB has become 'vile', peodophile' and 'rapist' to achieve another.
There's certainly a very prevalent view on this forum, particularly amongst its owner and his right hand man - that because CB has no previous history as an abductor or killer then it means he's unlikely to have committed the crime. You don't seem to have a problem with that argument?
But actually, it's completely off-topic anyway, this thread is about my (and others) apparent lack of a moral compass because we share the police opinion that Madeleine was abducted by a stranger and likely murdered. Do you think that makes us immoral? If so, why? Are the police immoral too for pursuing this line of investigation? Do you think they "get off on the fantasy" that this is what happened to Madeleine, because that is what we on this forum are being accused of - is it a fair accusation in your view?
I realise there's absolutely zero chance of you posting an on topic response but I thought I'd ask anyway.
