Socialism is when your wife is someone's else's girlfriend.
(Jokes aside, I think it's supposed like Co-ops, or employee owned businesses, or whatever, at least that's what it used to mean)

It is an evil departure from God that creates suffering and death.
Co-ops and employee owned businesses depend on markets (of money or trust/barter) and private property to function.
Socialism tears away and weakens the foundation of human civilization, which is the God given Right to our own property.
