What is wrong with setting up a community to live by their own rules (so long as freedom to live within that community is voluntary)? Are you not suggesting that you support the way the 14th amendment is currently being applied - ie that the beliefs of the majority are more important than private property right?
As far as "beating" and "correcting" or "disciplining" goes, those are up for interpretation. What is discipline for one person might indeed be abuse to another. Why should the communities people live in not be the best judge of what is what?
