@LukeAlmighty There was no enemy - it was a virus.
A common enemy can bring people together, when it is possible to paint him as an absolute evil that needs to be fought.
But a virus is a force of nature, no conscious enemy - it has no morals and cannot be "evil".
There are accepted ways to fight a force of nature - putting sandbags against a flood, as an example.
But mandating people to wear special clothing marking you as one of the good people, or locking people up in their homes and destroying their businesses is no acceptable way of fighting a force of nature. These are methods of tyrants, and tyrants will be fought by the good people.
