Let's be grateful to all those who came in before us. Grateful to all those men and women, young and old alike, who paved the path forward for us, brick by brick. To those men and women who marched across the bridge in Selma on that great day, those men and women who rallied behind the Gandhis and the Mandelas every single time they were needed, to those men and women who stood up for voting rights and civil rights and gay rights and equality and justice and a free world, those men and women who invented the future by inventing things that fundamentally changed the world from the electricity to vaccinations, from airplanes to birth control pills, from the printing press to the internet.
