This is not a time of extremes. This is not a time of extreme crisis. The world is not ending. We are not at the end of goodness. We are not at the end of democracy. We are not living in the most racist / sexist / ageist / classist / divisive / time ever.
How do I know? A solid knowledge of history is immensely helpful to put things into perspective. Does that mean there are no more challenges left? Of course not. But we need to approach these challenges in a way that is focused on solutions. We need to keep people in dialog, make change that is actually sustainably, and keep building coalitions.
If you seek change, you need to change hearts and minds, otherwise, you will only create resentment, and the change you seek will be undone easily. You do not build a house that is supposed to last for decades without a foundation, and you do not make political change without laying a solid, patient groundwork.
Patience is hard, especially if lives are at stake. Moderation is hard if there is a sense of urgency. I understand this completely. But unless the solution you seek can be allowed to wither away again, moderation is the key to success. Had Gandhi followed a different path than the one laid out by Thoreau in his “Resistance to Civil Government”, there would not have been Indian independence. Spartacus held the moral high ground till he allowed his followers to exert revenge on the Roman civilian population. Both Martin Luther King jr,. and Malcolm X expressed their righteous anger at racism, but both advocated for peaceful solutions eventually. Peace works violence (including verbal violence, and violence against objects and people) fails. The bomb may have ended the war, but the UN sustained the peace. There are plenty of other examples.
Moderation is true strength. Holding back anger, frustration, desperation and impatience is difficult, but it will pay off eventually. Giving in to these impulses looks superficially strong, but will discredit itself.
