I recently saw a clip of antitheist 'comedian' Ricky Gervais on the Stephen Colbert Show using the I believe in one less God' schtick. When he said it he made that 'laugh now' facial gesture at the audience.
But the question is this....who is his audience since to a theist the statement is a) obvious and b) an unsophisticated and indeed ignorant statement about religion and comparative religion?
Atheists though get moist about it so I would move that Gervais is playing to the gallery and making a horse laugh argument which as it seems passes as fair comment in the whacky world of Celebrity Atheism.
If any atheists here 'get it' would they please inform us how this is a 'devastating argument which reduces monotheists to gibbering wrecks' and atheists to gibbering post orgasmic wrecks.
The main point isn't, of course, that if there are 'n' purported gods that I do not believe in n and you don't believe in n-1. That is the starting point.
The really point about this 'schtick' as you call it is to challenge the theist on why he or she does no believe in the n-1 gods, yet somehow criticises the atheist for not believing in n - and often (as you regularly do) demands that atheists provide proof for the non-existence of god. If that is reasonable then you also need to provide proof for the non existence of Thor, Odin, Vishnu etc etc.
The point is, Vlad, that in relation to Thor, Odin, Vishnu and thousands of other purported gods you act in exactly the same manner as atheists. You choose not to believe in their existence due lack of any credible evidence that they exist. Further you'd (rightly) reject any notion that you have the onus of proof in relation to your lack of belief in Thor, Odin, Vishnu and thousands of other purported gods, placing the onus of proof on those who make a positive claim for their existence. So if those arguments are OK for n-1 gods for you they are just as valid for n gods for an atheist.
That's the point.
There is also the further obvious point that when a theist challenges an atheist for not believing in god (often in a higher-than-though and patronising manner) the response should be 'which one' and for mono-theists the point is that except for one god ... well ... neither do you.
