As America nears its 250th birthday, Juneteenth exposes the 89-year gap between freedom proclaimed and freedom enforced — and warns that rights still demand vigilant defense. This summer, America turns 250. There will be fireworks and parades. Speeches about liberty, about democracy, about the bold promise written in Philadelphia in 1776 — that all men are created equal, endowed by their Creator with certain unalienable rights. It will be grand. It will be loud.
