You assume that there is, or should be, one authentic you, but that's just not the case for most people.
Everyone has at least three personae. - the one you show to family members, the one you show to friends, and the one you show at work, and you may have more. Each one is authentic, but they're authentic to the specific context that you are in.
For example, I rarely swear at work - I have to be very frustrated or angry to do it there. A few minor words may slip out from time to time when I'm talking to family, but again, they don't hear it from me very often. On the other hand, with some of my friends I swear all the time.
In real life you can usually understand the context you are in pretty easily. Online it also used to be pretty simple - you would have one or more handles that you would use on different sites, and you generally acted appropriate to the image you presented using that handle. But now Facebook wants to combine all of that. They can present it as simplifying things for you - after all, you no longer have to manage all these different accounts right? But it also means that no matter where you are, you have to decide which "you" to present.
This is going to cause problems. --Those of us who understand the consequences are likely to either avoid sites that force you to authenticate through Facebook (this is my option), or start treating Facebook like Linkedin and do your best to prevent anything that may present you in an unflattering light to a potential employer. Young people aren't as likely to get this right away, and I fear that it's going to hurt them in the future.
