Here's a clip from a 1981 NAACP convention speech, where President Ronald Reagan addresses "a few remarks to those groups who still adhere to senseless racism and religious prejudice, to those individuals who persist in such hateful behavior."
"If I were speaking to them instead of to you, I would say to them, 'You are the ones who are out of step with our society. You are the ones who willfully violate the meaning of the dream that is America. And this country, because of what it stands for, will not stand for your conduct.' My administration will vigorously investigate and prosecute those who, by violence or intimidation, would attempt to deny Americans their constitutional rights."
