Group libel- what is fact and what is opinion

[Volokh, Eugene]

    I think that's right, and it's very close to Bresler:  Calling
someone a "blackmailer" in certain contexts means "this person's actions
-- which are factually not in dispute -- are morally similar to
blackmail."  Likewise with calling an abortion provider a murderer, or
calling the officials responsible for an execution murderers (again,
assuming that reasonable people would understand the statement as just
passing moral judgment on agreed-on facts, rather than a claim that the
abortion provider secretly stabbed a competitor in a dark alley).
