Here's a couple of quotes I found on the subject. No apology though and I wouldn't want to hang from the end of a rope waiting for one. It would all be put down to "noo light":
WT 1966 7/1 p. 391 Equality for All-Regardless of Race or Nationality
Because it is God's will, equality of rights and privileges for all races and nationalities is certain to be realized. However, it will not be as a result of any civil rights movement or present-day social reform. Prejudices and hatreds are too deeply engrained. Throughout human history man's attempts to eradicate them have miserably failed, and continue to fail. Understandably, some human observers feel inequalities are inevitable.
Yet what man has failed to do, God will soon accomplish. How so? First, by bringing about the destruction of this wicked system of things and preserving alive only prejudice-free servants of God into his new order. Then the promise of Jesus Christ, recorded in God's Word, will be fulfilled: "All those in the memorial tombs [regardless of race or nationality] will hear his voice and come out." (John 5:28, 29) Under the righteous rule of God's kingdom these multiracial, multinational resurrected ones will learn to live with one another in peace, free from previous hatreds and strife.
That an administration operated in harmony with the principles of God's Word can bring about this effect is apparent by examining the present-day organization of Jehovah's witnesses. It is a matter of public record that Jehovah's witnesses practice brotherhood of all races and nationalities, and do not merely preach it. With genuine affection they call one another "Brother" or "Sister," and they also treat one another as equals. To obtain a foregleam of how equality for all will be realized in God's righteous new system of things, associate with the organization of Jehovah's witnesses and see it in practice today.
Awake! 1987 6/8 p. 23 Part 7-1960-1969 The 1960's-A Period of Turbulent Protest I Have a Dream"
In the war of protest, students may have taken the lead, but they were not alone. For example, the U.S. civil-rights movement was supported by blacks and whites of all ages under its leader, Southern Baptist preacher Martin Luther King, Jr. In 1963 over 200,000 people marched on Washington, where King inspired them with his "I have a dream" speech.
A measure of success was achieved when the U.S. congress responded with what has been called "the greatest outpouring of human rights legislation in this century." And personal success came when King was awarded the 1964 Nobel Peace Prize.
Watchtower 1956 10/15 pp. 612-613 Is God a Segregationist?
Today true Christians follow that good example. They follow the Christian principles of love, pointing to the blessings of God's kingdom as the only real solution to all of earth's problems, and announcing that under that kingdom rule there will be no segregation on any basis but a oneness of all mankind under their Creator, Jehovah God.
Far from teaching segregation, the Bible condemns it. Paul publicly rebuked Peter for being ashamed to be seen with the uncircumcised Gentile Christians. And he wrote: "There is neither Jew nor Greek, . . . for you are all one in union with Christ Jesus."-Gal. 3:28, NW.
Then what should the true Christian do about it all? He does not spend his time trying to solve all such social problems, because neither Jesus nor the apostles took such a course. They did not agitate against Rome's occupation of Palestine or even against the actual slavery that was common then. They stayed free from such issues so that they could do their far more important work of pointing to God's kingdom as man's only hope.........Men of all races are examining the Scriptures. They are seeing this wise course and are teaching others of the glorious conditions of peace that God's kingdom soon will bring to earth. The blessings that this God-directed kingdom will provide will prove once and for all that God really does love all men who serve him, and that he is no segregationist.
