I think ['March'] is not just for the Black Lives Matter movement. It's for everyone. We all have to understand what happened then, so we can understand what's happening now.

This generation is different. They are not as interested in chasing money or material possessions. I believe that this generation is more interested in seeking social change and a more just society than any generation since those that brought about the civil rights movement and the struggles for human dignity of the 1960s.

I hope March is a guide for today's activists. It took raw courage for young people to volunteer to go to Mississippi in the summer of 1964, and unrelenting faith in the power of democracy to organize such a massive campaign.

What crystallized the importance of speaking out like that - of making nonviolence not just a tool or a tactic, but a way of life - was in San Diego [at Comic-Con]. One of the young girls who marched with us was wearing a hijab, and she came up to me afterward because I talked about my beard, and I talked about why I was doing it, and she came up and she gave me a hug, and she was crying. And she said, "Thank you. You have no idea how the other students treat me because they're shown that this is OK by Donald Trump. Thank you for speaking out."

People forget that many of the aspects of the Selma campaign were laid out in response to the church bombing in Birmingham.

I think people who agree with Donald Trump have repeatedly made the case that he should be able to say whatever he wants to say, it's time someone did that. But as we go and speak to the kids, the young people who are reading March, we see the fear, we hear them tell us how scared they are.

I think ['March'] is not just for the Black Lives Matter movement. It's for everyone. We all have to understand what happened then, so we can understand what's happening now.
