So we cannot let the actions of a few define all of us. The demented individual who carried out those attacks in Dallas, he's no more representative of African Americans than the shooter in Charleston was representative of white Americans. Or the shooter in Orlando, or San Bernardino, were representative of Muslim Americans.
They don't speak for us. That's not who we are. So when we start suggesting that somehow there's this enormous polarization and we're back to the situation in the 60s and it's just not true.
