"When a so-called history teacher at a state sponsored institution
makes statements about a dead man on Moscow mountain and in the
process impugns his character is that not libelous?"

Is Sean Quinlan the history teacher, and Wil Hendrik the "dead man on
Moscow mountain?"  I've read Dr. Quinlan's most recent article, and I
found no example of Wil Hendrick's character being impugned.

Would you care to elucidate?
