Healthy skepticism is good. It saves us from being too naive or too cynical. But it is impossible to preserve democracy when the well of trust runs completely dry. The freedoms enshrined in the Bill of Rights and the checks and balances in our Constitution were designed to prevent the self-inflicted wounds we face today. But as our long history reveals, those written words must be applied by people charged with giving life to them in each new era. That’s how African Americans moved from being slaves to being equal under the law and how they set off on the long journey to be equal in fact, a journey we know is not over. The same story can be told of women’s rights, workers’ rights, immigrants’ rights, the rights of the disabled, the struggle to define and protect religious liberty, and to guarantee equality to people without regard to their sexual orientation or gender identity. These have been hard-fought battles, waged on uncertain, shifting terrain. Each advance has sparked a strong reaction from those whose interests and beliefs are threatened. Today the changes are happening so fast, in an environment so covered in a blizzard of information and misinformation, that our very identities are being challenged. What does it mean to be an American today? It’s a question that will answer itself if we get back to what’s brought us this far: widening the circle of opportunity, deepening the meaning of freedom, and strengthening bonds of community. Shrinking the definition of them and expanding the definition of us.

I never inhaled.

Our democracy cannot survive its current downward drift into tribalism, extremism, and seething resentment. Today it’s “us versus them” in America. Politics is little more than blood sport. As a result, our willingness to believe the worst about everyone outside our own bubble is growing, and our ability to solve problems and seize opportunities is shrinking. We have to do better. We have honest differences. We need vigorous debates. Healthy skepticism is good. It saves us from being too naive or too cynical. But it is impossible to preserve democracy when the well of trust runs completely dry.
