That said: Incest? Really? I vaguely remember from my anthropology class that incest was one of the few universal taboos we know about. Universal taboo meaning that no culture/society allows it. In fact, the theory behind incest being a universal taboo is that there IS something in our nature that prevents it.
Definition of incest specifically?
Someone on fb recently described 1st cousins together as incest. However-in our state, 1st cousins can legally marry and have children it is NOT considered incest.
This would be a good example of different cultures having different definitions and therefore different expectations.
Some cultures consider it incest for an older relative to marry a younger relative-but other cultures see nothing wrong with marrying a man in his 50s to a child in their early teens-and often they are related in some manner (uncle/niece or 2nd cousins etc).
