Serious or sarcastic? I can't tell!

From time to time, I read a response from someone that just blows my mind because their ideas are so alien, so outrageous and yet I understand that they are perfectly serious in regard to what they are saying. Their statement is a true reflection of their mind. So be it.

Even more rare is the post that not only blows my mind, but also leaves me wondering if the comment is a serious comment or a sarcastic comment disguised as a serious one. Such is the case with the following comment I recently read as a response to an article attributed to lay author Sarah Palin (actually ghost authored for her) entitled Copenhagen's political science .

So what is your vote on this comment? Is it seriously how someone thinks? Is it sarcasm disguised as a real sentiment? I'd like to hear from you!
