I don’t think simplistic portrayals of history and ideologies – like yours – are very helpful.
Here is my version: Identify which concepts, ideas and methods turned North Korea to the state it is today. Discourage the use of those concepts, ideas and methods whenever they are proposed. This is probably best done by pointing out errors or inconsistencies or by presenting alternatives.
They even have bona fide anti-tyranny credentials: http://en.wikipedia.org/wiki/History_of_the_Social_Democrati...
And that’s just one example.
I should probably clarify that I really have no qualms with the first sentence of the grandparent’s comment. A generalization, maybe, but markets do work great in many situations and freedom created tremendous wealth and happiness. I just think that you shouldn’t use the term “Socialism” in the way the grandparent did. It just has too much history and too many ideas, concepts and methods connected with it.
Isn't what they aim for more like "social insurance"? Insurance seems to be a concept that can be reconciled with capitalism.
All I wanted to say is that they started out with Socialism and didn’t turn everything they touched into North Korea. Which means that tyranny is not the logical consequence of Socialism.
EDIT: I'm sorry to say, but it seems like the majority of people in the US use this word a lot without having any idea what it really means. It's become empty, a visceral cry, bypassing rational thought entirely. This too shall pass, I guess, but for now it's pretty sad.
Even Milton Friedman was in favor of redistributing wealth: http://en.wikipedia.org/wiki/Negative_income_tax
