Why does it take disaster to bring people together??

This was originally published on 9/10/15... I am sharing it again, in honor of those who died in the attacks on Sept. 11th, 2001!  It is also to honor those men and women who had a choice to flee the horrific events or stay to help save anyone that they could!  Many selflessly died trying to save total strangers! Why does it take disaster to bring people together??

Sorry, this is a long one, but once I started, I couldn't stop!

I was watching a video on 9/11 and thinking to myself that it's like a horrific scene from an action movie... what else could it be... for something this unthinkable could NEVER happen in real life! Suddenly a thought occurs to me:
On Sept. 11, 2001, we came together as one nation under God! As people either scrambled away from the tragedy to safety or into the nightmare that is now Ground Zero to put their lives... at risk for a fellow human being... nothing mattered, NOTHING, but surviving and reaching our loved ones.
There were no perceived differences that separated us! Nobody stopped to ask you who you were before they helped you... they just helped. It didn't matter what car you drove, what job you had, the color of your skin, your religious beliefs, your sexual orientation, who your parents were or if you were a Democrat or Republican. We were all just people... we were all Americans! We were one!
Our tears were the same, we all bled the same color, our broken hearts continued to beat despite the pain... and in exactly the same way! We instinctively knew that we had to work together to survive... and we did! As a matter of fact, much of the world... THE WORLD, banded together to reach out to the United States!
People... what are we doing now? Are lives in 2015 less valuable than in 2001? If not, then why are we are killing each other? Honor those who died on 9/11 by valuing your life and the lives of your fellow humans! We are One People, we need to act like it!
