"You can't mislead me by telling me what a real coin actually did" is implying any amount observation of a real coin only aids the likelihood function.

that since bayesian methods account for both the likelihood it is real and the likelihood it is not real, the observations are gaining evidence AND counter-evidence together. So as long as you don't lie about what a real coin did, then you are describing the actions of a real coin and therefor cannot mislead
