What's normal or not is partially culture-bound, as was already stated. In the U.S., we meet someone new and in 5 minutes, we might reveal our entire psychological and relationship history. In other parts of the world, it would be taboo to discuss personal matters. Also, there's the distinction to be made about harm caused by a behavior. If a behavior or belief causes emotional or physical harm to self or others, that's a problem. I believe in a life force or instinct. But, that's just my particular lens.
