Transcript for White nationalist Richard Spencer and Antifa member meet
Against abackdrop of racial tension, last weekend's violence brought two terms, alt-right, and antifa, into American households. They're terms that extremist groups use to describe themselves. Tonight watch two of their leaders face off in front of our cameras. Here again, ABC's Tom llamas. Reporter: After months of documenting their fight for a fractured America we brought white nationalist Richard Spencer and antifa member lacy Macaulay together for an encounter which didn't involve police barricades or weapons. Hello. I'm lacy Macaulay. I would prefer not to shake your hand. Reporter: It doesn't start well. I could smell the antifa activist from yards away. The foul stench of never bathing. Reporter: Macaulay refuses to condemn that infamous punch Spencer took on inauguration day. But lacy, I've got to stop you there. A punch in the face is a punch in the face. Genocide is genocide. I'm sorry, but I don't think anybody has sympathy for people who are actually advocating for policies of yen o'side. I'm not. You would like a white homeland. And to me that says genocide. People are going to suffer. People are going to die. I have no respect for that -- I don't want anyone to die. Reporter:: Spencer blames antifa for most of the violence between the groups but also insists his people will defend themselves. We're never going to win by unilaterally disarming ourselves. We're going to win when they know that if they punch us we're going to punch them back so hard that they never knew what was coming. . Reporter: But isn't, that excuse me for using the phrase, a B.S. Argument? Because if the goal is an all-white homeland, that is the goal, how do you do that within the laws of the United States? This is a big ideal for the future. Reporter: The southern poverty law center shows us the numbers. There's a rise in hate crimes and they directly attribute the rise in hate crimes to you specifically. They mention you by name. What do you say to that? That's total . And the splc is total . What is a hate crime? If anyone on the alt-right instigated violence, I would dissociate myself with them totally. The antifa is instigating violence constantly, and they aren't just instigating violence against me. They're instigating violence against random people in trump hats. When they attack your rights, you fight back. Speech is not violence, and violence is not speech. Reporter: Well, words are powerful. Words can change the world. A word is not a bullet. Reporter: While Spencer yearns for a white homeland, Macaulay dreams of an anarchist utopia. You want to deconstruct government -- I would like to actually bring power back to the people. We need to bring power back into our communities and neighborhoods. Good luck. Not if we have any last little breath. You're not going to stop us. Because you don't matter. Yes. We will stop you. Ultimately peep like me give meaning to your life. Guess what? I wouldn't care about you -- You wouldn't have a life without me -- Oh, my goodness. That is absolutely -- I'm sorry, but like news flash. I do a lot of work actually -- you are a little small part of this. Reporter: And with that the two agree to remain enemies. But with more protests scheduled for the weekend it's possible this won't be the last time they see each other. But back in charlottesville, where a young woman died in the streets, a show of unity against hate. Those who loved her most now hoping Heather Heyer did not die in vain. So remember in your heart, if you're not outraged you're not paying attention. And I want you to pay attention. Reporter: At her funeral her mother issuing a call to action don't look the other way. You make a point to look at it and say to yourself whatan I do to make a difference? And that's how you're going to make my child's death worthwhile. I'd rather have my child, but by golly, if I've got to give her up, we're going to make it count. Reporter: Reminding the country that no matter how the argument is framed by far right extremists what is important are the ideals America has always aspired to, that all men are created equal. For "Nightline" I'm Tom llamas in New York. Our thanks to Tom llamas and his team.
