David Friedman analyzes, with prejudice, the use in argument of loaded words such as “homophobic.” Such words, used thoughtlessly, confuse and indicate confusion on the part of the speaker. Used artfully, they are rhetorical bludgeons intended to stifle rational discussion at the point where rationality would be most helpful.
(Note also the comments to the post, including one comment that straightforwardly defends the use of dishonest words, in a way that unintentionally makes the opposite case, though the comment is perhaps a parody.)
