Both types of behaviour are frowned upon by our society, to the point that they can be considered taboo. A taboo is an implicit (although sometimes it can be explicit, like through the enactment of a law) prohibition of something, because it is believed that the act goes against the agreed cultural or religious beliefs of a community. Establishing those kind of limits helps communities to be more organized and to have a stronger sense of "belonging." On the other hand, it can isolate those who think differently and cause the community to be closed to new ideas.
