Unlikely that there&#x27;s a single cause. One possibility is that people&#x27;s value systems differ: do you like smoking? Do you like eating bacon? Do you like sunbathing? For each, there are people that disapprove, or would like you not to do this, or would even ban you from doing so (I could pick more controversial examples, but these are sufficient). Conflict clearly exists - but a way of resolution is not clear at all.
