scaremonger
(n.) A person who invents threats to themselves and others everywhere. A form of critic looking for a lucky break to be proven right. Typically praises other scaremongers, 1984, hates the government, organised religion and trading systems while freely using the produce of any. Quite narrow minded and insecure, but will attract a lot of sheep.
I have the unfortunate trait of sometimes being a scaremonger.
