Democracy is good at stopping socialism

The purpose of democracy is to enable the people to be protected from crime... by giving them an objective arrangement of property rights. But if there is first-past-the-post then voters will not be able to vote in a naive manner and they will be reduced to tactical voting. If voters must vote tactically they are not voting for their preferred candidate (by definition) and they are being disenfranchised. Only if we have proportional representation are voters being given the full expression of democracy. If we do not have (full) democracy then it is possible for politicians and the state to exploit this anomaly to their own advantage. If we do not have pr then the politicians can exploit the voters in the name of socialism. Pr is much better than fptp at stopping (unwanted) socialism... whereas they are both able to stop crime in the normal fashion. Proportional representation stops both (unwanted) socialism and crime but fptp is able to prevent only crime... it is not good at stopping socialism. Both systems can stop crime (in the traditional sense of home invasion and personal assault) but only pr is truly capable of stopping harmful socialism.
