I personally would not participate in a topless marathon. I personally think it would be degrading to women. However, I bet you may find people that would. Doing a topless marathon in support of breast cancer research, some people may be willing to do anything. That being said, I think there would be alot of controversy.

I would but I feel it would be demeaning to women and would not be a good idea for them.

I don't think that getting people to donate to see boobies is a very good way to raise money for something that should be respected. Breast cancer isn't funny. I see where there going but, don't many women with breast cancer end up losing their breasts? In that sense I think it's sort of a rub in the face to those women. Look.. sex sells.. and you don't have one your sexual organs anymore.

Personally I think if someone wants to show their boobs to the world fine, but don't pretend you are dishonoring yourself to be charitable or noble. Way to prove women still get furthest on their looks.

So far the only people to respond to this question apparently 'just don't get it'... For starters, mammary glands are *not* sexual organs, they're for child-rearing. Second, the popular puritanical abhorrence of public breast-feeding and visible nipples is a sexist repression (contrary to the Bill of Rights), since men are not subject to such proscriptions against going "top-FREE". Third the perpetuation of that cultural taboo, despite a woman's right to bare her chest just as men may, is tantamount to female-on-female misogyny. Besides, regular women's breasts---without the advantage of video-editing and suggestive clothing---are nothing much to look at, and if more women embraced their right to go top-free whenever it suited them (such as Gwen Jacobs of Guelph, Ontario, did, and does) the public novelty would assuredly quickly wane. This is not to mention the psychological liberation and empowerment women gain from asserting themselves boldly: akin to bra-burning taken to the next logical level. I think a Top-Free Marathon in support of any women's issue is a fabulous idea!
