OK - Jet - let's say that I wish to refute Amnesty International's, and the United Nations' number (below), can I mention that you are my source? (Even if the number is less than 1.7%, that's still a significant number of people with intersex traits.) No need for insults about 'common sense', as I've merely linked to the research. Moreover, people don't advertise that they were born with intersex traits. For example, Jamie Lee Curtis supposedly has Testicular Feminisation Syndrome, but doesn't discuss it (not that I know of). And if you go to major cities in India, there is a good chance that you will see a kinnar (hijra) if you are outside long enough, or if you are near a wedding. Some of them go to weddings to ask for money, because their blessings are supposed to be good luck. And if no money is given, they curse the wedding and cause a scene.
