Mrs Monkey, no one is saying that child abuse should be ignored, so please, calm down.
Unfortunately we live in a world where you have to be careful whatever say and where you say it, no matter what the subject. What you have to ask (having not seen the advert) is could the subject matter have been approached without implicating another, quite innocent group?
Like I say, it's the world we live in, good or bad. It could quite easily have been any other section of our society being implicated, would it be fair on them?
