What an interesting debate!
Some very different views expressed (thank you all), and without any personal rancour, thank you again.
For the record, I have sunbathed topless, and if I were ever on a beach warm enough to take off my thermals, I probably would again, despite having a lot more scars than I used to (just a WLE for me) and, much more obviously, an awful lot more cellulite and wrinkles everywhere else! But only if I weren't the only person doing it, I wouldn't want to upset the status quo on whatever beach I happened to be on.
I do not believe that you can equate topless models (what are they supposed to be modelling anyhow?) with normal people with normal bumps, lumps and imperfections. I am not and never have been any sort of 'model' physique. I wouldn't be in the least bit concerned (perhaps a little jealous mixed with a little proud of my babies) if any of my daughters decided to sunbathe topless, but I WOULD be bothered if they decided to 'model' topless in a smut-rag like The Sun. Similarly I'd be rather upset if they took up stripping, topless waitressing, prostitution or pornographic films.
I agree that page 3 is not just about showing off a female body, it is about objectification of women. And please don't suggest that there should be lots of pictures of young, nearly naked men in the papers to even things out, that is also objectification, and does nothing for me, personally. I much prefer to see sportsmen and women, fine specimens of humanity, looking fit and healthy - a lot more pleasing to the eye and soul, and a much more positive image for both sexes to portray.
There is no place in this day and age for the very out-dated practice of displaying nubile young women specifically for the purpose of men to ogle at them. As said above (sorry, forgotten who by), the ideal would be for body acceptance.
I went to Finland a few years ago and visited the local municipal swimming pool. Attached to that and every other public pool was a public sauna - mixed, of course. Signs outside clearly forbad the wearing of swimming costumes in the sauna "for hygiene reasons" - I kid you not! - but you were expected to bring in a towel for sitting on, again for hygiene reasons. Everybody did, but said towels were the size of a small hanky. It was not a sexual or titillating experience at all, and there were all ages and both sexes, skinny, fat, young, old, smooth, wrinkled, and it was great that nobody was bothered. THAT is the sort of reaction the human body should generate, not silly giggling or tittilation. Except, of course, when an individual is engaged in sexual activity - privately - with a chosen partner.
Sorry, rambling a bit. Now to find that petition and sign it.
