idolatry is in the bible, does not match opI guess a key component is the intention and principle behind the practice. Brushing your teeth is about good hygiene, it affects both others and yourself. The ways to keep ourselves sanitary and healthy have changed over the centuries with the changes of technology and in some cases increased knowledge, but the idea behind the various practices have been the same.
So I'd think unBiblical practices would be either ones that harm others or that involve harmful spiritual practices such as idolatry.
