I'm staying out of all of this, but i'll opine on the legal side - defamation requires statements of fact and not opinions. To the degree his rant deals with facts - like claiming someone did or did not do a thing, that's at least possibly actionable. But the opinions are not actionable as defamation. So for example: "bob murdered someone" - actionable "i don't like bob" - not actionable. Depending on what gets said, etc, it may be actionable as something other than defamation.
