yes there are readers and there are readers.... each one will
have a different mentality,so it is the job of the writer to
convince those people who do not readily believe whatever they read
and see,only then will such an article be a well written piece,if
not like what you said those readers already have some ideas on
those points mentioned,they would already not be reading it with an
objective point of view since they will be basing on their own
views to judge the article and not based on info from the article
to decide if it is true.
