Martin is himself very sensitive and his "attacks" are only a kind of first strike as part of his defensive strategy. He cares deeply about folk music and regularly posts above the line (in the non-BS section), furthering with his eloquent postings a deeper understanding of the tradition in the rest of us. He is a sweetie, really, and don't you denigrate him.

(Mmmm... this is good grub, dear - where did you say you picked them mushrooms?)
