Just saw a New Atheist (complete with the self-description of "gnu atheist") over at Valicella's blog. The cult-like behavior practically glowed off his responses.
* Constantly talking about "we". As in "what we, gnu atheists, believe". You know, because he's a representative. Because he's even conducted a single scientific poll. Not only making use of this word and imagined position, but doing so incessantly - practically every other sentence is "we gnu atheists believe" or "we gnu atheists want".
* As mentioned, he was pretty much pulling gnu beliefs out of his ass. "Gnus are against pseudoscience!" Well, every person thinks they're against pseudoscience. Even the timecube guy. The idea that gnus are - as a group - against eugenics though? That's laughable.
* Defending the idea that anyone or anything lacking a belief in God is an atheist, expressly including spark plugs. So, you know, apparently I flushed an atheist down the toilet this morning, and Magic Johnson became ill when his body was adversely affected by various atheists invading his body. Anything at all in order to avoid being put on the defensive, it seems. Including sounding creepy and crazy.
* Insisting that most people understand evolutionary theory adequately, then admitting he has no data on this. Remember, science is important, but don't let that stop you from making claims about whatever you want when the data is lacking. Likewise for the 'gnu atheists focus on arguments for theism that are bad and popular because that's why most people believe in God'. Right, because - given Dawkins' mangling of Aquinas' and other's beliefs in his own book, we can trust gnus not to construct strawmen? We can trust them to even be aware of them?
But really, the whole thing was just freaking culty. In my anecdotal experience, the creepier religious people I've ever come into contact with communicated much like this. The irrationality, the droning, the hivemind attitude. I get the impression that the one benefit of someone coming up with that 'gnu' label is you'll be able to identify a nutjob and/or a supreme asshole far more easily now.
