I didn't downvote you, but my guess is that your comment came off as an attempt to push Randianism, or perhaps some other closely related ideology. I'm pretty sure that wasn't your intention, but the problem is that many such people are highly active on the internet, and "collectivism" happens to be a word that they use incessantly and which is not very common otherwise.
So they were engaging in exactly the kind of nationalism Orwell describes. How fitting.
I have found this most wonderful (if fairly lengthy) article, and thought you would enjoy having it brought to your attention.
It is so good, I think we should include it among the references in the "Politics is the Mind Killer" wiki page. But, before that, I submit it to you, and ask you: is there anything in this article that would warrant its exclusion from this site? I mean, besides the fact that it is about politics, and written by a notorious Social-democrat (And is that in itself grounds for exclusion?).
