If you can't handle one little arbitrary political abduction at the hands of secret government police, socialism may not be for you.
Socialists protesting in Portland are learning that "The worst thing that can happen to a socialist is to have his country ruled by socialists who are not his friends." -Ludwig von Mises
See, you might not realize it, but the USA is already heavily influenced by the socialist/ communist philosophy of Karl Marx.
Socialism is more of an umbrella term, meaning centralized control of the means of production– like factories and farming– in the hands of the state.
Communism is more extreme, with complete abolishment of private property, and a dictatorial government that allegedly attempts to distribute wealth "to each according to his need," and extract labor "from each according to his ability."
