Are the 'Mothers Union' the right people to deal with this child sexulisation controversy?

I don't think they are, they seem exceptionally prudish and old-fashioned. The woman on TV was worried that her kids might see a picture of a woman in a bikini, and she was obviously embarassed by the word 'bikini', she hushed her voice as if naming some sort of bizarre perversion when she said it. I mean its an item of clothing that might be worn in hot weather or whilst swimming, it doesn't have to actually imply sex, a kid won't really notice it in my opinion.
