"I venture to think that it is a mistake to lay down a rule as
to libel on a class, and then qualify it with exceptions. The
only relevant rule is that in order to be actionable the
defamatory words must be understood to be published of and
concerning the plaintiff. It is irrelevant that the words are
published of two or more persons if they are proved to be
published of him, and it is irrelevant that the two or more
persons are called by some generic or class name. There can be
no law that a defamatory statement made of a firm, or trustees,
or the tenants of a particular building is not actionable, if
the words would reasonably be understood as published of each
member of the firm or each trustee or each tenant. The reason
why a libel published of a large or indeterminate number of
persons described by some general name generally fails to be
actionable is the difficulty of establishing that the plaintiff
was, in fact, included in the defamatory statement, for the
habit of making unfounded generalizations is ingrained in ill-
educated or vulgar minds or the words are occasionally intended
to be a facetious exaggeration. Even in such cases words may
be used which enable the plaintiff to prove that the words
complained of were intended to be published of each member of
the group, or, at any rate, of himself (emphasis added)."
