It’s not often that I agree with Bill O’Reilly. So when I do, it’s notable.

Last night was such an occasion.

Liberal web site Daily Kos has a user known only as Mahler3. On Monday, he posted some pictures from Jenna Bush’s wedding over the weekend and juxtaposed them beside pictures of dead and wounded Iraqis.

Mahler3 says that the pictures are of Iraqis and that the death and destruction seen in the graphic photos were perpetrated by American soliders.

We’ll ignore for now that there is no proof of either claim.

Not surprisingly, O’Reilly, no fan of Daily Kos to begin with (he calls Daily Kos founder Markos Moulitsas “one of the most despicable people in the United States today"), blasted away on this post and the site in general.

I agree: The post is despicable. But don’t take my word for it: See for yourself here. (But BE WARNED: These images are graphic and are not suitable for young viewers.)

The post itself has been called “tasteless,” “deplorable,” “sick,” “pointless” and “beyond the pale”—no, not by Bill O’Reilly, but by Daily Kos readers themselves.

So here’s the point: When people like Mahler 3 do things like this, they discredit their own arguments, and the arguments of others in agreement with them. Whatever they are saying about the war is lost in the outrage over how they say it. Mahler3 argues with his fellow war opponents and insists that he was making a point in posting the pictures together.

And therein lies my point: Not even those who agree with Mahler3 on the war understood or agreed with what he did. What makes him think that anyone else would read his repulsive post and his convoluted argument and say to themselves, “Oh! Now I get it. If only someone had shown me a picture of a dead child next to Jenna Bush’s wedding photos long ago!”

Most war opponents know this; for proof, you need only read through the comments to see how poorly the post was received. Here are some examples:

Daily Kos readers had plenty to say about Mahler3’s post. I have just two words for it: Predictably disgusting.

By the way, if you feel led to drop Mahler3 an e-mail about his post, you can reach him at . But if you do, be prepared to receive a seriously vitriolic diatribe in response. Go ahead and e-mail him—but only after you add his address to your blocked senders list.
