The problem is that when it comes to local government, there basically are no constitutional limits. American government is constructed under the assumption that local government ought to be able to vary enough to support everything from communes to monasteries, rather than state or county governments enforcing a uniform notion of "normal life" with "normal" civil rights overriding local notions of morality.

If you live in a dry town and you're a drinker, you're supposed to GTFO, not complain about human rights.
