Definition of "afraid"

I went through the worst Ku Klux proposition in the country at the time it was at its height. And I had to go down to the Ku Klux meeting and tell them what I thought of them, and I wasn't afraid of them at all. And I'm not afraid of this situation because I think it'll work out in a way that when these people sit down and get a chance to think and study the situation, they're going to be ashamed of some of the things they've done.
