This reminds me of my time at the University of Washington in the late 90s. There was a guy just like this who would yell and preach about how the gays are all wrong and that. And he had a specially made electrical cord about a yard or so long, with male plugs at each end. He called it the 'homo cord' and would wave it in people's faces saying 'see? it doesn't work, there's no power'. I had the distinct pleasure of walking by one day when a girl who was watching him yelled out 'Try it from the back!'. Didn't stop him, though.
I've seen this guy in Ann Arbor, maybe a year and a half ago!
He accused the group of students that had gathered around him of being communists and seriously said, "The road to hell and to Moscow are paved with good intentions!!!"
