“One of the things I do worry about sometimes among progressives in the United States… is a certain kind of rigidity where we say, ‘Uh, I’m sorry, this is how it’s going to be’ and then we start sometimes creating what’s called a ‘circular firing squad’, where you start shooting at your allies because one of them has strayed from purity on the issues. And when that happens, typically the overall effort and movement weakens.”
— Former President Barack Obama, quoted by The Guardian.
