Well, I vote for piss on people.
Again, it's the situation and context on which a breast is..ahem..exposed.
I breastfed my son whenever and where ever "the need was great" . I wasn't in your face about it (except his little face, of course), and I never had a problem and I would have happy to have torn a "new one" for anyone that dared to give me any flak about it.
