That when all women everywehere can openly breastfeed, one of the biggest outcries will come from women who complain that men are looking at them doing it. Women will pull their boobs out . . and, somehow, it will be men who are charged with an offense!
Any open-breastfeeding law should include a provision that protects onlookers: If you whip it out in the public domain, you can't complain when people look at it. But, I won't hold my breath waiting for that provision. The only allowable defense will likely be blindness!
