I expect we'll get a wide spectrum of responses here.
As a German, I'm probably a lot less "shocked" by nudity. I'm not sure, though, whether this will necessarily help the lactivism cause. I've seen quite a lot of nude or "bare-breasted" women on beaches in France but to my knowledge, BF rates there are low nonetheless.
From the gotopless.org site:
|GoTopless was founded by the Raelian Movement, which recognizes that life on Earth was created by advanced extraterrestrial scientists. These scientists, both male and female, used their mastery of genetic engineering to create humans in their own image (breasts included!).
I think this is just a little too far out there for most people.
In Ontario it isn't an issue - women and men have the same rights to go topless.
