I am a feminist. But even I find that notion stupid, unless you're in a nudist community; then obviously it'd make sense. Breasts are a sexual organ and ergo it is biologically natural for other people to generally be attracted to breasts. And I don't know about you, but I'd rather not have to put up with being aroused every time I'd go outside on a hot day. It'd just be distracting and annoying. I don't believe it to be a double standard either as people without breasts...simply don't have breasts. Simple as that. Double standards only exist when the two subjects in question are on an equal footing. The fact here, is that people have different bodies. But that said, personally I'd prefer if both males and females kept their shirts on in public.
