So you say its damaging, yet contribute to it. Yeah that makes sense.
The consequences of favouring male genitalia, or 'drawing in excitement', over female;
"In Asia, the preference of many parents for sons over daughters has led to some 80 million girls "missing" from what should be the normal balance between men and women in a society, perhaps because they have been aborted, neglected, or directly killed. Yet while Americans may read with some horror the fate of female embryos and infants in Asia, they may not realize that American parents, especially fathers, also favor boys over girls. This preference for sons is less severe and subtler than in Asia, but it has consequences nonetheless.
The preference for boys, the authors find, seems to be largely driven by fathers. At least since 1941, men have told pollsters by more than a two-to-one margin that they would rather have a boy. Women have only a slight preference for daughters. Taking all of this evidence together, the authors conclude that parents in the United States do have a preference for boys over girls.
The authors note that this preference for boys could matter more in the future. Technology already permits parents to choose a baby's sex, but the methods are now costly and unreliable. "As the cost of procedures falls and their reliability rises, the sex-ratio in the population may slowly become more male," Dahl and Moretti conclude. "More importantly, the bias for boys evidenced by our results may lead to worse outcomes for daughters."
