I posted this in the Trump thread because it is by American Poet, William Stafford. It is just as apt here

Learning

A piccolo played, then a drum.
Feet began to come—a part
of the music. Here came a horse,
clippety clop, away.

My mother said, "Don't run—
the army is after someone
other than us. If you stay
you'll learn our enemy."

Then he came, the speaker. He stood
in the square. He told us who
to hate. I watched my mother's face,
its quiet. "That's him," she said.
