(Note I frame this in probabilities; citing one or two governments that you believe are socialist and are doing it "right" will still leave it a very risky move when considered against the whole of everyone who has tried it. And I'm not particularly convinced that you'd consider them "real Socialism" if it weren't momentarily convenient for this argument, because all the European countries you might want to cite still have poverty and social and wealth inequality, etc.)
Either way, the cost/benefit analysis of "trying to bring about Socialism" has some rather hard-to-ignore things in the "cost" column if you ask me, not to mention a certain lack in the realized benefits column, so don't be surprised when I react poorly to the idea that we should try it where I live.
