I loved They Live before the pervert's guide to ideology, but you're right that this post is probably derivative of the latter. It's just a daily blog post that we're doing as part of Winter Break Of Code, and wasn't really "meant" for the front page of HN, so I'm surprised to see it in a place like this.
For what it's worth, I wasn't trying to write an analysis of They Live, and was just using it as a tongue-in-cheek back drop for a different question.
