Paranoia "the immigrants are out to get me" or "the government is out to get me". There is some evidence of each but generally this info comes from people suffering from paranoia. If consensus reaches that indeed the government is wiretapping and such then in a functioning society the voters will educate and push for the reforms... and society isnt functioning currently.
In local areas it is water rights. Internationally it is i need to start a war to prevent war. There are so many out-there ideas that are tried on like clothes in any context.
