Martin Luther King Jr.
This quote is from his 1967 speech entitled THE OTHER AMERICA, given at Stanford University:
"Abused and scorned though we may be, our destiny is tied up in the destiny of America. Before the pilgrim fathers landed at Plymouth we were here. Before Jefferson etched across the pages of history the majestic words of the Declaration of Independence, we were here. Before the beautiful words of the Star Spangled Banner were written, we were here. For more than two centuries, our forebearers labored here without wages. They made cotton king. They built the homes of their masters in the midst of the most humiliating and oppressive conditions. And yet out of a bottomless vitality, they continued to grow and develop.
And I say that if the inexpressible cruelties of slavery couldn't stop us, the opposition that we now face, including the so-called white backlash, will surely fail. We're gonna win our freedom because both the sacred heritage of our nation and the eternal will of the Almighty God are embodied in our echoing demands."
