That is a good start and we must take care not to stop there. The risk with social questions is the temptation to give social answers. To look at 'sides of a story'. As well as absorbing social perspectives it is necessary to look at the raw science. To look at the behaviors of mammals in general and in particular those of the apes that have mating patterns similar to ours. To compare and contrast the expected outcome of game theoretic models with our observations of human behaviour. The answers those investigations give are not always popular. They also don't always match the stories that we like to tell ourselves!
