Debilitating mental condition afflicting brie-scoffing liberal relativists and ivory-tower dwelling elitists, as diagnosed by Alan Johnson, causing them to rend their garments in apopleptic rage.
The sole reason for the refusal of the Britsh public to embrace Muscular Liberalism in its entirety, symptoms of Neoconitis include disruption to sensory perception, susceptability to conspiracy theories and strong allergic reactions to bullshit.
Typically, sufferers will fail to recognise signs of social democracy in those who agitate for the replacement of established international law with a loose set of poorly defined statements amounting to "The Republicans do whatever they like, no matter how deranged or self-serving."
Examples of mass outbreaks of Neoconitis include voters in the American Democratic Party primaries in 2006, who went berserk, convincing themselves that lifelong socialist and humanitarian Senator Joe Lieberman was some kind of Republican hack.
In reality, Lieberman's record of near-total support for Republican chicanery over war, massive redistributions of wealth to the economic elite and bankruptcy bills that shaft the public for the benefit of credit card companies was a sign of his deep, committed Leftism.
