Lump everyone who disbelieves the McCanns together. It makes it so much easier to make it look like a campaign.
As far as I am concerned - there has been a 10 year 'campaign' by
some (not all) sceptics who when faced with the inconvenient fact that there is no evidence against the McCanns or their friends, have decided to devote their time to conducting the most vicious character assassination against them. The 'logic' behind that appears to be that if they can prove what a wicked, greedy, evil, lying couple they are - then it must be them wotdunnnit.
Unfortunately for that group of sceptics, during the last 10 years not a shred of evidence has emerged regarding the McCanns private lives to confirm that description of them. In fact quite the opposite has been the case imo.
The answer to that problem appears to be to 'trash' everything they say and do - and also to 'trash' any person who dares to say anything which threatens the description of the McCanns which they want people to believe.
The fact that Emma Loach, who was stranger to the McCanns - but who - after eventually meeting and spending time with them was able to form her opinions on a one to one basis, should be recognised by all reasonable people as having credence imo.
However, the habit of immediately dismissing anyone and anything that is even remotely positive about the McCanns is so entrenched in some quarters that all reasoned logic has also been 'trashed' along the way.
AIMHO.
