A disheartening aspect of the art world of the 1980s was its willingness to
indulge in ad hominem attacks disguised as a defense of certain values.
The problem is so bad that even deliberate attempts to foster reasonable discussion can
end in ad hominem attack or sanctimonious dismissal.
They misrepresent evidence, engage
in ad hominem attacks and other fallacious arguments, they continually premise shift, when challenged they change the subject, they use obfuscation and argument by assertion; they are funded by people with a vested interest in a particular conclusion; and more.
