You are correct unless we look at one of your premises, namely, "God's wishes/rules cannot be considered in matters such as these, as that would mean that the state would be establishing religious beliefs". There's a difference between a just law that affirms a religious belief, or coincides with a religious belief, and a law that establishes religious beliefs--and in the USA, now, by the way, not Russia or places under Sharia. It would be wrong and unconstitutional to have a law "You must worship on Sunday." It is correct to have a law "do not murder" even though that is a specific Bible law as well! The desire, often appropriate, to not have a law establishing religious beliefs in no way implies that all laws must contradict religious beliefs. Quite the opposite since common law and precedent law both have themes of inalienable, god-granted rights. You are suggesting bodily autonomy is appropriate in this debate based on an inalienable under-God right to pursuit of happiness, to freedom. Yes? No?
