Hey, I like frappacinos.
Just kidding.
People tend to have differences, it comes from having a free will and personal priorities. You will therefore always have conflict. Conflict causes seperation and strains a society. With this you get a lack of interest in promoting and celebrating common things like citizenship. When a major catastrophy occurs against a certain group, then that group will usually come back together and unify. That's what we are seeing now.
Unfortunately, under normal times, in the lack of a greater enemy,,, we will fight with each other.
I am not saying that what has happened recently was good nor am I happy about any facet of it. But,,, it is interesting to note that something like this can help us to see how trivial many of the things we were worried and bickering about last week are not worthwhile any more.
