What sceptics fail to notice is that they ARE supporters (of Amaral, of Grime, of the dogs (“dogs don’t lie”) of every blogger who slagged off the McCanns and poured vitriol onto people like Mitchell) whilst us supporters are deeply sceptical of Amaral, of the dogs, of propaganda-pushing, bile-vomiting bloggers like Blacksmith. So, don’t think you are imbued with special superpowers that us plebby supporters don’t have, we have them too, it’s just that we have them correctly targetted. 
I can only speak for myself, and I have not accepted anything anyone has said unquestionably. I understand why the McCanns were made arguidos, which their supporters claim to find incomprehensible. I can see no reason to accept that what the McCanns have said is the truth. I accept very little of what the media has said as true. I cannot understand why Operation Grange investigated only stranger abduction given the paucity of evidence.
The McCann supporters have chosen to believe uncritically what the McCanns, the media and the UK police have said. When a child has disappeared everyone's evidence should be examined and questioned, there's no room for belief.
