YABU. It's up to the woman if she wants to make a living from showing her tits. And most of them aren't exactly postponing a career in brain surgery. It's their only chance to earn serious money. And if they do go on to become brain surgeons, they've paid off their student loans

And why are we demonising breasts anyway? Seriously, there are bigger things to worry about. If you want to start some sort of feminist crusade, what about female circumcision? Or just Google "acid attack", and you can find several sites concerning certain countries where this is common in order to punish women who reject male advances.
Breasts are normal, healthy things. There are bigger battles to be fought.
