Lenny Flank and PZ Myers, both positive atheists, are going for each other’s jugular on Panda’s Thumb. Myers thinks Flank is harming the cause because Flank refuses to agree that theists need to be lined up and shot and Flank thinks Myers is an idiot because Myers is alienating people in numbers so great that political defeat is inevitable. Flank is right of course.
At any rate, the exchange is largely between the two of them and is at 510 comments and counting as I write this. For a laugh – check it out.
