I do not accept FSM.
I do not accept unicorns.
I do not accept allah.
I do not accept odin.
I do not accept any god concept.
If I accept a god concept, then I am forced to accept all these things.
How does that follow?
To accept one and not all the others IS CONFIRMATION BIAS.
How so? Looking at a physics/mathematics monograph in which the authors both admit bias and present a theistic cosmology we find:
"Human nature interjects popular or ones personal myopia. In early times the theological bias that everything in Gods universe must be perfect perfect spheres for example kept discovery of the heliocentric universe at bay for thousands of years. Such bias is human nature. We must confess a similar bias; but we do not profess a theistic cosmology solely for alignment with out belief system. As we hope to demonstrate in these chapters; it is the explanatory power of the anthropic cosmology that prospers the underlying predilections." (emphases added)
Amoroso, R. L., & Rauscher, E. A. (2009). The Holographic Anthropic Multiverse: Formalizing the Complex Geometry of Reality (Series on Knots and Everything Vol. 43). World Scientific.
Imagine I found their argument persuasive and thus concluded that their following claim is true:
"We propose that teleological or eutaxiological bases are tantamount to the essence of anthropic cosmology itself suggesting that the anthropic principle entails an additional action principle driving or guiding cosmological evolution in opposition to the postulate of random Darwinian or naturalistic evolution of Big Band cosmologies." (emphasis added).
Perhaps I am also swayed by arguments such as those in e.g.,
Beauregard, M. & O'Leary, D. (2008). The Spiritual Brain: A Neuroscientist's Case for the Existence of the Soul. HarperCollins. [NOTE: I hesitate even to call the above garbage an argument]
Copan, P., & Moser, P. (Eds.). (2004). The Rationality of Theism. Routledge.
Manson, N. A. (Ed.). (2003). God and Design: The Teleological Argument and Modern Science. Routledge.
Moreland, J. P. (2010). Consciousness and the Existence of God: A Theistic Argument (Routledge Studies in the Philosophy of Religion). Routledge.
Polkinghorne, J. C. (2007). Quantum Physics and Theology: An Unexpected Kinship. Yale University Press.
& innumerable others similar to the above.
I am then persuaded about an entity requiring particular properties. For example, the classical "logical" arguments presented in the The Rationality of Theism (e.g., the ontological argument, the cosmological argument, the teleological argument, evidential value, etc.), if they persuaded me, wouldn't give me any reason to believe anything about Odin or unicorns. Same for a theistic cosmology in which the creating agent must necessarily have particular properties that most deities in various religious practices (past or present) lack, let alone mythical creatures.
There are general and specific arguments for theistic/deistic/religious entities or beliefs that, whether they are believed to be sound or not, do not entail acceptance of any and all "supernatural" beliefs. Likewise, if I accept that unicorns exist, I am not therefore logically required to think that UFO abductions occur or that Leprechauns exist in order to avoid confirmation bias. In fact, certain religious worldviews are situated in deliberate contradiction to others, such as the "watch-maker" deistic god of many a post-"Enlightenment" intellectual is to the person, theistic god of mainstream Christianities. Therefore, if I accept a deistic god I automatically must preclude the existence not only of personal god from the Abrahamic religions but also all pagan gods (by "pagan" I exclude here all "neo-pagan" beliefs/spiritualities and include only those religious/cultic practices of pre-Classical, classical, late antiquity, and the medieval period).
I'm not following your logic.
