Yep, I know what you mean. Plus I don't think people quite understand the effect that drug addiction and alcohol has as well, I can't think of many cases where this was not an aspect of the problem, even if it just meant the kids were neglected so were essentially easy prey. There is so much more (sadly) to the whole thing than just the stereotypical evil paedophile, there's a whole manner of other stuff and it's not easy to pick your way through it. Plus for anyone who tries to understand or deal with the problem you get the whole 'they should all be strung up by their ***' brigade.
The work I do now has opened my eyes massively to it all and they weren't exactly closed to it previously (my parents were foster carers for the first 11 years of my life), I admire my consultant massively, and her juniors and anyone who can work in this field and still come out of it a decent and un-jaded person. I absolutely could not do what any of them do and they do make a difference, just unfortunate that for every child they make a difference to, there's another load who go unnoticed.
