They still exist, those who call themselves "communists" and "socialists". How to beat them - in a discussion - for good? At least argument for that they should shut up! Here's an idea.
First you ask the Socialist: "So you want to abolish private property?" This will be answered with a: "Yes. It is oppression and blah blah.."
Next is to ask: "Well, you are wearing some clothes and perhaps you have something to eat at home." The answer: "Yes, I have to own something in today's exploiting free-market society to keep up my strength to fight private property rights."
Then a question: "But in a society with no private property, you would still need to have clothes and food to eat. How will you keep your clothes on and swallow the food if it isn't your property, and yours to dispose of or use for your benefit?" The answer: "Society will provide all with sufficient clothing and food."
Then a question: "What if society will not be able to afford clothes and food for you and decides you are not worthy of such great gifts, perhaps because you offended the majority of the society?" The answer might become a clumsy, "they would never do that because Socialism will have transformed everybody into good persons", or the more realistic (and historically more accurate), "then so be it if I am to be killed with starvation and cold - I will obey the society and the majority of the people in a Socialistic society!"
This final answer will have proven than a person does not own one's body because society can, in not allowing any private property, take a person's live without direct physical aggression.
But since the Socialist is going for a social order which does not accept self-ownership, why in the hell is this person using his or her own body to express these opinions? Do the means justify the ends? Can an opponent of self-ownership, with good conscience, show up in an interview and use his or her body without asking "the society" for permission first?
I guess so. In the absence of reason and logic, no conscience can exist! However, without permission from "everyone", the Socialist should shut up! At least according to own logic!
