I'm not going to paste you, OP but I think there are some distinctions that should be made.
Some people were actually abused.
Some people know people who were abused.
Some people fall in to neither category but have been affected by the stories of abuse.
Nobody can say how anybody else should be feeling but I think that the almost gleeful postings looking to blame somebody for scheduling a programme that contains something related to an abuser isn't helpful to anybody in any category. It just winds some people up and it should stop.
I never much liked the song 'Two Little Boys' but actually, it doesn't affect me particularly. I fall into the first category, by the way, but not by Rolf Harris. I might feel differently if I had. Anyway, I can still appreciate that he's done horrific things and he deserves every punishment that's coming his way but it doesn't detract from the fact that he is a great artist and public performer. He has lost all of that and has the knowledge that he's reviled now across the world. I'm just sorry that Saville never got to realise the same thing.
I think that it's very unhelpful to everybody to condemn TV schedulers and somewhere along the line, we have to be the adults and switch the TV off when we don't like the programme. If we really hate something then we have the right of complaint.
The abuser is often somebody quite close to the person and that person may have loved them very much. That's why it's quite difficult for some to read the revulsion from people who haven't personally experienced it and therefore can't comprehend the complex feelings and despair.
I find all these threads quite 'triggering' to be honest and, even just the titles make my heart sink.
