Not only social media I might add. Traditional media also has a role to play here. They are generally more critical of these types of groups, but they also seek ever more ridiculous stories to tell, in order to get an audience -- so even a story that questions the theories of these groups but reports them as "one view among others" is problematic. It is the structure of our media/advertising landscape that keeps nuanced but true views below the average interest and and amplifies outrageous crap, since it generates clicks and eyeballs.
