Most opinions are not false or secondhand, fallen misinterpretations of academic source texts, but partially true, firsthand, risen interpretations of reality or bioconditioning. Academic arguments are cleaner and more formalized, but don't bear the scars of the real.
As just one example, there are legitimately academics going around all upset at the pseuds who misunderstood plato and not realizing that the perpetual re-emergence of platonism is itself compatible with and even necessitated by the premises of platonism itself.
