Erm....either a particular god exists, or it does not exist. There is no false dilemma here. I've already said I'm arguing specifically against the Christian god - although I would argue the level of evidence for most posited supernatural entities is on about the same level, that is to say, none.
And again, this is simply not a case of taking evidence against one position as evidence for another. It's a matter of what constitutes a standard of good evidence, and do I consistently apply that?
Would you believe in Russell's teapot, if I asserted it to exist? After all, can't prove it doesn't exist!
Would you believe in the Flying Spaghetti Monster, if I asserted it existed? After all, can't prove it doesn't exist!
Would you believe in unevidenced entity X, if I asserted it existed? After all, can't prove it doesn't exist!
Do you get it now?
I would wager you don't believe in the existence of far more values of X based on the argument from ignorance than those you do.
Ergo, you are being inconsistent as heck.
