Does your penis provide sustenance for another person? No. Can you show your nipples in public if you want to? Yes. Also, breasts are not genitals or sex organs. Only 13 out of 190 cultures world wide consider them to be sexual or even private parts. Don’t even act like this is a feminist thing. This is a babies-have-the-right-to-eat thing.
I’ve seen more men urinating in public than I have women breast feeding, like are you fucking kidding me??!? Men take every excuse to expose themselves in public to make women uncomfortable.
