Will Coronavirus further promote divisiveness or create unity?

In his inaugural address during the Great Depression, US President Franklin Roosevelt said "the only thing we have to fear is fear itself.” That’s as true now as it was then. Clearly, postponement of public gatherings, fastidious hand-washing, and avoidance of unnecessary social interaction are prudent measures for the time being. But what happens when it’s all over? Will we retreat further into our already divisive, insular worlds? Or will we discover new sympathies for others, including those with different political beliefs?
