Soapbox orator in town

In the sixties - 1963-1966 or thereabouts - I often went in to town on Saturday mornings. I often use to listen to a soapbox orator making anti-communist speeches in the Precinct. What was his name? And what became of him? Was his name Karl/Carl Carter? I think he formed something called "The Anti-Totalitarian League" Does anyone have any information?

I certainly remember him, but unfortunately have no idea of his name
