I know this: Most of us want to believe that we are better than the ugly and unmitigated racism the president has shown through tweets like those of today.

We fought a Civil War to prove it.

We sent federal troops into the South to desegregate high schools and colleges to prove it.

Civil rights workers — black, brown and white — suffered terrible beatings, incarceration and in some instances death to prove it.

And yet, here we are today with a president using social media and the great power of his office to try to bend back the arc of justice and bring the nation to a state of global disgrace.
