the problem isn't selfies themselves. There is nothing inherently wrong with a self-portrait.
The problem is actually social media and attention-deficit riddled facebook addicts who need constant reaffirmation that they have friends or "look hot". Of course, since most selfies that we are exposed to are low-res, low light garbage screengrabs of Joe (or Joanne) Nobody making funny faces or trying too hard to look serious (or sexy, or insert your own adjective here), the very act of creating a self-portrait is taking a beating. Let's not throw the baby out with the bathwater, please.
And don't forget that the act existed long before the phenomena nearly ruined it.....
