What is the point of it all?
It does nothing to help Madeleine McCann; in fact some of the campaigns have actively tried to derail Operation Grange from its inception.
How does the immediate family feel about constant referral to the costs. How does the immediate family feel about "What about all the other children?"
In days gone by it was done with green ink and capital letters and always had a stamp on the envelope, and the perpetrators were always despised. Now the internet serves the purpose and it is truly amazing the number of dedicated poison pen writers it has uncovered.
At least the green ink brigade perhaps had the excuse of actually having personal knowledge and perhaps a personal grudge or personal envy of the subject of their vitriol. I think to keep an internet campaign or rather a variety of campaigns going for an eight year period to attack a family you do not know and have never met could be considered a really weird thing to do.
I don't know what kind of family these folk come from but in my family if you injure one of us you have injured us all and I imagine that the McCanns and the Healeys might be cut from much the same cloth.
