People, come on. This is the stuff that Facebook is made for! Someone made an offensive, hurtful gesture where none was warranted. She passed it on as a little story like we all do to our friends and family in the year 2012, because it was an interesting event in her life, and one that had a personal cut to it.
What happened from there was not her fault. If other people thought it was interesting or shocking enough to comment on and share, that's because it was again, an interesting event. It's not like it's some group out to get us Mormons and make us look bad... A huge chunk of, if not the majority of the people outraged by it and passing it on are LDS. I can't find the post that I saw it on right now, but the LDS friend that shared it said something simple like, "Really? I thought we were past this".
The Church didn't do this, BYU didn't even do this. Anybody pretending that she was attacking either didn't read the post, and instead got caught up in some of the negative comments. BYU doesn't need "Mop Up" units, it does what it does well, and will be just fine. Same goes for the Church.
