I don't really have a boob in this whole public breastfeeding issue.
As a committed non-reproducer and cranky old spinster, my breasts are really more of an annoyance than a feature...in fact, the other day when I found yet another lump (don't worry, I'm just cysty), I started considering having them removed to save the trouble of more rounds of mammos and biopsies (needle and otherwise).
But as a human, I suppose I have to root for the continuation of the human race, which means feeding the darn things. I was surprised to learn from David Wescott via IzzyMom that Facebook doesn't feel the same way - they apparently allow pro-anorexia groups on their site but not breastfeeding pictures.
"Starvation good, feeding babies bad?" Is that how it goes? THAT seems kind of sick.
I could go on about the sexism and anti-woman/anti-child bias implied by this decision, but you're smart enough to connect the dots. It's a small battle, but I think it connects to a lot of larger issues, ones that are important even for people who aren't women or who don't have children.
Go check Izzy's post. She has some good links.
