Why was this mother "outraged" that someone posted a picture of her breast feeding in public?

Because it’s a violation of her own space by posting it without her knowing or without her consent.

It’s just as natural as going poo. But would you be outraged if someone posted a picture of you going poo in the woods on a camping trip?

If ou’re referring to the story that I think you are, it was also accompanied by negative remarks about her breastfeeding in public.
Do you have a link? The entire article that I read explains why she was outraged very clearly.

Is this the incident to which you are referring?

Interesting that you compared it to defecating, @zenvelo. Why not compare it to something comparable to breast feeding, like a picture of her drinking a glass of milk?

I agree, he was an ass, @canidmajor.

Yeah, @canidmajor is right, the article clearly states why this mother was outraged. Her pic was taken and uploaded without her knowledge and then she was criticized for breastfeeding in public.

OK, I agree, but would she have been just as outraged if someone had taken a picture of her eating French fries and posted it?
And so what if she was criticized for breast feeding in public? Anyone who does that is a jerk, but why should she care?

My point is, if there is absolutely nothing wrong with it (and I don’t think there is) then why should she care?

I think she is morer outraged over the comments and the apparent attack on her choice to breastfeed when the child is hungry as to ther photo itself. I am sure if he had posted something nice, like how dutiful a mom she was she would not be outraged.

I’d be pretty damned outraged if some stranger posted a picture of me, without my permission or prior knowledge, on social media with comments slamming my normal behavior.
She has grounds for at least civil, if not legal action, claiming that making her identifiable in a controversial situation could potentially put her in harm’s way.

The cataclysm is close at hand, I’m going to agree with @canidmajor . The schmo was wrong beyond belief.

Well, my ass also made the front page of our local paper. There was a crash on the street where my office is. I was bending over to fix some stuff on one of the cars to make it driveable, and the news guy snapped a shot. All you can see of me is ass.

@Hypocrisy_Central is right. In her own words, from the article that @canidmajor linked to:

“It is not the fact that the picture was taken, or even that it was put on social media that bothers me. If he wanted a picture he should have just asked, I would have gladly smiled,” Kendall continued. “It is the fact that it was done so in a way that aimed at shaming my child and I, as well as every other nursing mother, for taking care of my baby.”

There’s no implication here that she feels guilt or shame just because she didn’t want the guy to post the photo without her permission. I’m not sure why you think that follows from this story, @Dutchess_III.
