I think you expressed it well JK.
I don't really know enough about Childline and I reserve my opinion on Esther..she is probably well intentioned ..but
There is a similar woman in Oz-Hetty Johnson who is a real rabble rouser and sees "pedos behind every bush". She has caused endless anounts of trouble including the whole farce behind the photographer Bill Henson (with works in the Tate)who did some terific pics of 14 year old boys and girls just on the outset of puberty.
Hetty proclaimed them porn and all hell broke loose with the PM caling the pics "revolting" whilst the Opposition leader said he had Henson works on his walls.
However in person Hetty is a wonderfully nice person and ..well intentioned.
I note though she has just lost her government funding.
I prefer to give any money I can to a French doctor who runs an orphange in Thailand for abandoned kids with AIDs..he won't accept any government funding and has devoted nearly 30 years to the cause..the locals think he is a Buddha.
