There are numerous reasons why this is so, therefore I do not really see a huge unjust here:
- Breastfeeding on the news is different from an entertainment programme. News is meant to be factual documentation, whereas entertainment has been constructed specifically for said purpose. Putting breast feeding in could give the wrong impression of what the programme is about (ie. breastfeeding is shown so the viewers are getting sexual feelings because of breasts. Sad I know, but the programme directors know this is how the general public thinks).
- Breastfeeding on a film set would mean actors exposing themselves when they may not want to, causing more problems, when they could simply shove a bottle in the babies mouth.
- I doubt the babies you see in programmes like Hollyoaks are the actual babies of the female actors, so it's unlikely they would even consider breast feeding them. I know if I was a woman and mother, I would be the ONLY one to breast-feed my child.
About the watershed thing, if I've understood my research correctly, "natural nudity" is perfectly acceptable at any time of day. However, in almost all contexts, if you were to show breast feeding in "entertainment" it will be more than just "natural" as the programme is designed for that purpose.
I do not feel there is any descrimination between breast feeding on the NEWS from people in the developed world from those in lesser developed countries. It's simply that, like the other person said, we do not do breast feeding in public because of the taboo, which I agree, we should get over big time.
Hope my opion has helped you!
