"Obama's Speech at Selma, 2015"

by Barack Obama
It’s the idea held by generations of citizens who believed that America is a constant work in progress; who believed that loving this country requires more than singing its praises or avoiding uncomfortable truths. It requires the occasional disruption, the willingness to speak out for what is right, to shake up the status quo. That’s America. That’s what makes us unique. That’s what cements our reputation as a beacon of opportunity. Young people behind the Iron Curtain would see Selma and eventually tear down that wall.
