Not this again.

The idea of President Obama “photoshopping” images in order to carry out some kind of nefarious scheme has clearly gotten a death grip on the wingnut zeitgeist. They seem to assign some kind of mystical power to this meme; they believe that if they can finally convince the world at large that these pictures have been doctored, Barack Obama will be forced to hang his head in shame, immediately resign the presidency, and live the rest of his miserable life in his true country of birth, Kenya.

It’s wingnut crack. They can’t stop doing it, even as it destroys their brains.

Tonight’s episode in the Parade of Ridiculous Photoshop Outrages is brought to us by the always wacky American Thinker, where once again we have a so-called “Photoshop expert” who doesn’t seem to understand how JPEG compression works, zooming in and analyzing the pixels to impress the rubes: The Illusion of Obama’s Bin Laden Raid Situation Room Leadership.

I don’t even know what to say about this kind of bizarre right wing craziness any more. There’s no point in debunking it; first, it’s too freaking easy, and second, they just don’t care and it doesn’t stop them from repeating it endlessly with less self-awareness than your average parrot.

But here’s all you need to know about American Thinker’s “Photoshop expert” Mara Zebest: she’s been a Birther since 2008, and joined Arizona Sheriff Joe Arpaio’s “Cold Case Posse” to push the crackpot theory that Obama faked his birth certificate. So her credentials are impeccable for an appearance at American Thinker, but “Photoshop expert” is a bit of a stretch.

I have to say, though — Floating Hand Problem is a great band name.
