Which folk community is not accepting of Roger McGuinn? It seems to me that Roger is very much of the folk music community.
My own experiences with Roger have been very positive. In the 1980s, when I was running a folk club in Montreal, he came and played there. His concerts were a mix of Byrds material, that he played on an acoustic 12-string, and traditional folk songs. His audience was mostly folk music fans (and artists).
And in 1998 when he came back to Montreal, he did a long guest spot on my folk music radio program.
Ed Pellow mentioned Roger's Folk Den website. It's all about promoting traditional folk songs.
Roger's next album is going to be all traditional folk songs, all in acoustic arrangements and including duets with Joan Baez, Tommy Makem, Pete Seeger, Jean Ritchie, Odetta and Judy Collins.
