"Socialism" and "Socialist Policy" are huge tents - the definition implied by the GP comment is an extreme.
Sound bite dictionary definitions look like:
a political and economic theory of social organization which advocates that the means of production, distribution, and exchange should be owned or regulated by the community as a whole.
"Owned
or Regulated" as in the people police the commons and those capitalist industries that seek to profit from and supply to the people.
It's quite alright to laugh at those that take Harrison Bergeron as a socialist text and claim that the goal is to reduce everybody down to some lowest common denominator.
They are, quite literally, just being very very silly and attempting to invoke a bogeyman to scare children.
