"To clarify-=they dominated the folk music media"

There might be a very slight possibility that this applies to Pete - at least in the sense that dozens, if not hundreds, of commercial folk musicians were singing his material throughout the sixties. [I mean commercial in the sense that they were paid for doing so.] But the Smothers Brothers? They were neither particularly musical nor particularly funny, and it is either a miracle or an indication of how low the tastes of American TV watchers had already fallen (or maybe both) that their show lasted as long as it did.

Conrad, nobody here is trying to censor you, just as nobody ever tried to censor any singers/musicians on the right during the height of the last folk music revival. However, it doesn't seem that you are listening to what anyone else here has to say, regardless of how politely or rudely they choose to say it. You are entitled to your opinion, and I suppose that is true no matter how far from the facts of the situation it strays.
