It feels like we have fought this battle before. Why won’t it go away? Why are we here again?
Perhaps it is as simple and complex as that there are epic forces of good and evil alive in the world. Evil, whether in the form or racism, misogyny, selfishness, and so on, keeps coming back, even when we think progress has been made. That is the nature of the world we live in.
The answer: to keep flooding the world with good, keep fighting the good fight.
Do not lose hope.
