unnecessary breast feeding videos!

I used to work for the state department in the child care, as an infant teacher. Moms would come in pull out their breast and feed away! Never had a problem with seeing another women breast feeding their child. It was normal to me. 
But some friends post snaps and videos everyday of them breastfeeding like they discovered the holly grail of life and all I can think is geese I forgot what ur kid looked like without ur boob attached to their face with  some snarky comment below like "breast is best." some will send personal snap videos of nipple and all of them BF. 
 Now I understand the need to feed ur child and being comfortable to do it in public. I don't mind. baby's hungry feed the baby. but what I don't understand is the need to have an audience and snapchat it and send it to ppl who obviously can care less. 
Like awesome ur feeding ur child good for u, ur not a neglectful parent what do u want from me a cookie. Let ur child eat in peace damn it. 
Now I'm not gonna lie I'll prob take a photo or two of my bundle with their head nestled in my chest but I won't be sharing. I don't see the need of an audience. And I don't think the baby needs one either. 
Most BF moms are on here complaining about how BF needs to be normalized in public. Well normally I don't have an audience watch me eat they know I'm eating but they don't stare. And I doubt you'd want someone to stare well u were just trying to feed ur baby. The best way for ppl to act normal is to mind there business and not stare. So Wth is normal about sending a video to ppl over there trying to mind their own business. It called over sharing. What am i supposed to say in response?  "mmm looks apatizing." Wth. I responded to one saying "Thanks for showing me how it's done I was worried I forgot." 
UPDATE: 1st off in response to some comments. I have a child already That I breastfed till my milk ran out for 3 months, Then formula fed. I know how to BF and yes it's very empowering, but like some ppl said some ppl do it to prove a point and that's what it feels like especially now that I'm pregnant again. it's disheartening to mothers who tried but it didn't work out for them, and it's just not necessary to send personal videos to ppl. I can speed through their story but a personal video seems very directed. 😒 I feel like now that I'm pregnant I have a sign on my head saying plz show me how it's done cuz I asked for your unsolicited advise. I also tried to delete one off snap but kept them on FB where they don't post that much and they later confronted me about it. 😳 It was awkward to say the least. I don't mind her in person, I just could do without the post and videos. Plus she obviously didn't get the hint and was hurt that I deleted her. Because I value our friendship and have to see them every so often, so I can't just delete them.  I tried.
