There are sooo many worse pics on FB than a woman nursing her baby. In fact, someone who has photos on his page that I would NEVER want my kids looking at (it shows a very scantily clad woman crouched at crotch level to a man holding 2 guns, so not only does it objectify women but it also glorifies violence) is someone I feel very close to. Over my time living in the American South, he and his girl (who is currently expecting a boy) became very close to me and my man. And no matter how I feel about his pics, I would never EVER flag his pics because they are publicity for his movie and that (acting and rapping) is how he feeds his family. I know him to be one of the nicest guys I have ever met!
And this isn't even one of the bad. It doesn't really bother me, but I have a hard time believing people would flag the "Nurse-In" because of sexual, violent or offensive content but then leave stuff like this all over the damn place.
