Liberty/oppression and authority/subversion where authority and liberty is seen as good makes a good policy inconsistent with itself. There are aspects of each that mess up the aspects of the other. Meaning a "good" policy would be hypocritical.
I know it means that stuff like police in a liberal country is inconsistent with liberty, but the concept of freedom is inconsistent with itself anyways so meh.
Also, one could argue that sanctity/degradation is another name for liberty/oppression. Loyalty/betrayal is also another name for authority/subversion.

And now I read the rest of the post. It's propagandist moralist rubbish to me; while interesting, I give you that, I'm interested in what exactly he's trying to point out.
First off, the article is a dumb branding of liberalism as something non-moralistic; "We have a moral system which divides good from evil, they're not evil, they just have an incomplete moral system". When was it a good thing to vote for the more moralistically fundamentalist party?
Also the article American-centric and does not concern with actual ideologies or moralities but rather specific American political parties; but I'd assume it wouldn't be a problem because American politics have an issue discerning ideological fundamentalism from politics.
So summary of my post; it seems like a condenscendation on moral high ground where he instills conservatism as the morally better system. It's just problematic as the real world isn't fantasy. I would care less if I voted for Chaotic Evil Orcs or Lawful Good High Elves. All I want is to be happy and the good/evil dichotomy should have no place when it comes to making political decisions; that very dichotomy is part of the reason why some Islamist states have such humongous issues arranging for their peoples prosperous.
