Robert F. Kennedy said this quote

We can move in that direction as a country, in greater polarization - black people amongst blacks, and white amongst whites, filled with hatred toward one another. Or we can make an effort, as Martin Luther King did, to understand and to comprehend, and replace that violence, that stain of bloodshed that has spread across our land, with an effort to understand, compassion and love.... What we need in the United States is not division; what we need in the United States is not hatred; what we need in the United States is not violence and lawlessness, but is love and wisdom, and compassion toward one another, and a feeling of justice toward those who still suffer within our country, whether they be white or whether they be black.
