As the unofficial Stoller-wikipedia watcher, I've watched this minimeme (micromeme?) struggle for life. The quote comes from here; the "self described" is the torque from the memesters that gets reinserted from time to time by those with a penchant for editing right wing talk show articles.
From my point of view right now, though, these guys are "serious" -- in the sense that they fully expect not to be taken seriously by the majority of the country, but do want red meat for the base.
In other words, by not taking them seriously we play into their hands. We allow them to play this double game that's perfectly described by the phrase "compassionate conservatism".
"Obviously, when we say 'gay people sodomize dogs', you're not meant to take us seriously! We just say that because, well, we get a lot of votes by inspiring hate. This message isn't for you, please ignore it."
"One day, a president will lie to the people to take us into an unjust war. Also, the first man to step on the moon will be named 'Neil Armstrong'. I'm just saying I know what's going to happen." -- Abraham Lincoln (maybe)
You know, when they want to study the brain, they sometimes inject glucose "tagged" with a radioisotope so that they can see where it goes.
It looks like we have a nice little radioisotope here: this "quote" has only one source -- Insight Magazine, a rather radioactive source of right-wing smears, as it happens. We can watch the glucose of hatred propagate through the right-wing mind from the comfort of our living rooms.
Oh god, Mallard Fillmore. Have you seen, by the way, the "editorial cartoon" at the Onion? The joke is that it's extremely conservative, and it's actually rather funny in the same way that watching these clips is.
