SteveH,
What on earth are you on about? I'd've thought my earlier post was clear enough.
I'm talking about the tendency of religious types to call their branch, group, sect, sub-sect, micro-sect etc the "only true" subscribers to a particular faith (think the Peoples' Front of Judea), and often too to condemn (or worse) the rest for getting it wrong. You know, Freud's "narcissism of small differences" and all that.
Which group of atheists do you consider to be the only true ones?
It's not a claim necessary for atheism.
