No you are correct. My response would be that an inefficient cleansing is still a cleansing. At this time we do not stop intersex people from procreating. We do highly stigmatize in society and we do traumatize them by denying their existence as natural and forcing/pressuring them to undergo extreme operations. Isn't this a more PC way of intentionally limiting their reproduction?

Imagine if you were playing a game where you had to obtain 100 signatures to win and before that game I told everyone else in the room that you were a child molester, and if they gave you their signature that meant they wanted a child molester to win. It would make it significantly harder for you to win right? This situation is analogous for the intersex person's situation in a society that views anything existing outside the traditional dichotomy as unnatural. They are stigmatized. It becomes significantly harder to find a job, mate, to feel self-worth, build confidence, trust, all the things humans need to successfully establish themselves and their genes in society. Sure, there is a lower tier of society bracketed off for them. They can work in the carnivals, whorehouse, etc, but they are in some sense blocked from "normal" society.

It would be interesting to look at suicide and marriage rates among hermaphrodites in Europe and America. Which would you guess is higher?
