The legislation was passed because people saw a need for it and lobbied for it?? Oh, the horror!
As a mom who has occasionally run into the need to breastfeed in public, I'm pretty happy about being able to do it without being harrassed. I have also always been discreet, and I doubt that anyone has noticed what I was doing.
I sincerely disagree with your choice to characterize all women who have done this on occasion as "screaming-faced" people who are just looking to flash their breasts, because this is just clearly not true.
Do I agree that there are some breast-feeding women who do it in public just to get in people's faces? Yes. Is this the majority of breast-feeding women? Definitely not.
That's activism.... It's like any other demonstration to change tolerance, sometimes it works, sometimes it offends. Activism exists as a counterforce against the types of attitudes here.... the equal and opposite reaction to "women should stay home until the child is weaned."
