That’s an incredible video. I actually see this group once in awhile. There are 4 or 5 of them, always with the same speaker, who set up behind the subway entrance adjacent to Macy’s on 34th and Broadway every once in awhile. I never stopped to listen to them preach. They always draw a small black audience, though I remember once an Asian woman getting in a heated argument with the speaker. They also usually have someone off to the side videoing the proceedings.
