Why are we still talking about this?

A friend of mine posted this hilarious breastfeeding meme on Facebook and I could not even wrap my head around how the commentary got to a few dozen about it.  Everyone talking about what they do and what is/isn't acceptable.
"What's so wrong with the bathroom?  I don't mind it."
"My husband prefers that I cover, but I don't care what others do."
"I prefer to be modest."
"I never use a cover, baby hates it."
"I don't see why a woman can't cover up if it makes others around her uncomfortable."

Nursing while covered up? Nursing while uncovered? Using formula? Well good for you!  You're feeding your child!  I am a huge proponent of breastfeeding.  But I am also someone who had some major issues with latch and subsequently with supply, so I know the struggle is huge.  I had to stop after six months of breastfeeding and switch to formula to save my sanity and be a better mother to Little Man.

I just don't get why this is even a discussion.  You don't see people debating where, what and how other adults should eat... so why is this happening with infants?  Oh yes... because of BREASTS.  Those two lumps on a woman's chest that bare nipples.

The real problem nowadays lies within the media and the hypocrisy of today's society.  Photos like the one above have been reported and removed from Facebook.  But replace that woman with a teenager or Victoria's Secret model and that baby's head outline with a bra, then nobody thinks twice about it. Why is this?  Because everywhere we go, we are taught that sexy is good.  Sexy is awesome.  The better your body looks in underwear (or even naked), the more you are to be praised.  The purpose of the breast has shifted from infant nourishment to something to be sexually objectified.  How messed up is it that a woman is indecent in the photo above but a woman with the same amount of cleavage not nursing a child isn't? 

This conversation shouldn't even be happening anymore.  Women should be able to breastfeed their child when, where, and however they wish.  It shouldn't even be up for discussion what is acceptable and what is not.  What's acceptable?  Feeding your child when they are hungry.  Boom.  That is the only true and right answer to this "conversation".  What blows my mind is that we are still having it.
