Vision America has a nice article on how dissenters from scientific
orthodoxy
, be it global warming or evolution, are mocked, ousted, and
persecuted just like religious heretics.

Scientists who dissent from the alarmism [over global
warming] have seen their grant funds disappear, their work derided, and
themselves libeled as industry stooges, scientific hacks or
worse….Some have gone so far as to propose that “global warming
deniers” are aiding and abetting a global holocaust and should be
prosecuted.
 
A new report from the U.S. House of Representatives has condemned
officials at the Smithsonian Institution for imposing a religious test
on scientists who work there. And it suggests their attacks on a
scientist who just edited an article on intelligent design are just the
tip of the iceberg of an industry-wide fear of anything that suggests
man might not have come from a puddle of sludge.
