Your police departments, fire departments, the armed forces and the FBI. Your roads and bridges. All socialist.
That's nonsense. There's nothing inherently socialist about the government organizing, funding, and controlling certain sectors of the economy that are necessary to the functioning of a nation. Some of the above could conceivably be contracted out to private entities but the headaches involved and the reduced accountability to the people makes that a tough sell. Although, we might see more inept cops fired if they were privatized, so perhaps it's worth a crack?
Why not health and education?
