A person who believes in the principles of socialism. Key amongst these is the belief in the duties of the state to the individual and the individual to the state. In socialism power rests with the state and the individual's rights are second to those of the mass of people, the state. These principles are found in many countries across the world, some example countries are Britian, Germany, France, Japan, Israel and Australia (these coutries are joined by many others).
A notable non-socialist country is America (although socilaim is not anti american, just anti poverty and corruption, so america just happens to be in the firing line)where the followers of the republican party are keen to denounce socialist principles as communist (they aren't) and to protray socialism as giving enterprising people's money to those who don't work. This common misconception is partly responasible for American's world beating selfishness and the existence within that country of areas so poor they are lower in HDI than areas of India.
The people were opposed to the socialist candidate, taking the money of the enterprising to give to layabouts. The hard working indivduals of the postal sorting offices, cube farms and factory production lines were bitterly against giving their hard earned money to those layabout congressmen, smoking execs and the lazy 'business' consultants. Yep that socialist guy was bad
