On the second day of the Democratic National Convention in Denver, a “truther” organization called We Are Change sponsored the convention’s “9/11 Truth March.” I didn’t expect more than a few dozen people to show up, but was surprised and a little disturbed at how large it actually turned out to be — the crowd numbered in the hundreds, not the dozens.

I really, really wonder what thought processes go through these people’s minds; I’ve been photographing truthers for nearly six years now and I still don’t have the slightest clue as to what motivates them.

Aside from the obvious: Dementia.

Or: Naiveté.

It doesn’t matter how many times their conspiracy theories are debunked (such as WTC Building 7, as shown here); they just plow forward and keep believing, facts be damned.

The usual cast of governmental villains were imprisoned in “God’s Gitmo,” which I suppose is the modern term for “Hell.”

This was an interesting riff on “Recreate 68.” It seems the truthers want nothing less than to overthrow our government in a total political revolution.

This sign might have more accurately read, “10 Conspiracy Theories Leading to Insanity.”

Here’s the We Are Change truck. They reject Obama and McCain, because they’re obviously both in on the Big Lie.

The War on Terror is a ... hoax? You mean, I don’t have to wait in line at the airport? Alright!

Masked faces, UFO buffs — that about sums things up.
