A statist is just about anyone who's not an anarcho-capitalist
Someone who believes in the practice or doctrine of giving a centralized government control over economic planning and policy.
A statist believes in extremely heavy government intervention in personal matters and moderate to high government intervention in economic matters. They generally believe in a centralized state with a social safety net and strong laws restricting personal liberty.
Someone, who out of fear, ignorance or a sense of misplaced duty blindly follows the rules of a government without considering whether those rules are fair or just. Giving the state the benefit of the doubt as opposed to the citizens of the state. Unfortunately, most statists will never receive the special treatment from their government that they think they have earned or deserve.
Anyone who believes the official story about anything and uses the word "conspiracy theorist" is probably a statist.
