When those white men wrote our constitution, they enshrined the democratic principle of "one man, one vote." It took nearly 150 years, one war, and multiple amendments for that principle to be interpreted as including non-whites, non-males, and non-property owners.
"Freedom of religion," enshrined in the Bill of Rights, originally meant the freedom from a national religion, but until the 20th Century it was interpreted as the right to oppress religious minorities. People were hanged in colonial Boston for the crime of being Quakers, and lynched in the early 1800s in Philadelphia for being Catholics.
Trumpism has brought our antidemocratic demons out into the light, where maybe we will have a chance to deal with them. Some days, when I feel my years, I think I'd rather not. But for the sake of all my Gen Z heroes--Greta and Malala and the rest--I'll slog on. Because we writers are the conscience of the nation.
