That's because it's stupid. Hash tags don't free hostages. Action does. The Bring Back Our Girls Internet campaign, if you can call it that, is just a way for politicians and Hollywood celebrities to feel good about themselves.
Whoa wait a minute. Are you saying hashtags dont free hostages?
Even if its just a way to feel good while bringing attention to the issue why is that a bad thing again?
It's a great thing, as long as no one pretends it will make any difference in the eventual outcome of the situation. Heck, if Obama can get the Nobel Peace Prize for getting elected president, he should get the Medal of Honor for this.
