Right, so let's say in the future we can test and it's determined that Michael Phelps has alien DNA, and we have overwhelming evidence that aliens athletically outperform human men, and that requiring human men to compete against aliens in athletic competitions unfairly limits human men and will generally mean human men have no opportunities for participation in competitive athletics. Then we have these conversations about how to both protect aliens access to athletic competition, and human men's access to athletic competition.  | 
							
						
 This would be applicable if the IAAF were making decisions based on people's genes. But they're not. And then, of course, there's the implication that Caster Semenya isn't *really* a woman.  | 
							
						
 "A biological woman"? Seriously?  | 
							
						
 NP. What is your issue with that term?  | 
							
						
 Being intersex really does make a huge difference. Most women do not have internal testes producing testosterone, which makes a huge difference in how a person’s body develops during puberty. Semenya doesn’t have testosterone levels that are on the high end of the range for females but instead has levels that are in the male range. That makes a big difference in physical development and strength.  | 
						
 Having long arms and floppy feet also really do make a huge difference. Also, there is no one "being intersex" thing.  | 
							
						
 1. What does it mean? 2. PP is saying that Caster Semenya isn't really a woman (whatever that means).  | 
							
						
 Not the PP, but you are erasing all of the different ways in which someone can be a biological woman. Semenya was born a girl and raised as a woman. One assumes she has "girl parts" and either XX chromosomes or some variation thereof. She is biologically a woman by literally any standard one could apply.  | 
							
						
 1. It means a female human, with XX chromosomes since birth. 2. She's most likely an intersex male, with XY chromosomes and internal testes, who's body never developed external male genitalia due to a genetic mutation. So she appeared female at birth and to this day, but has male genes and has developed physically more like a male than a female.  | 
							
						
 If she has the intersex condition she is understood to have, then she has external "girl parts", and internal "boy parts", and XY chromosomes. That is not a biological woman.  | 
							
						
 There is literally no evidence that she has one intersex condition or any intersex condition at all. Her testosterone levels are high, but that's not proof that you personally understand what condition she may or may not have.  | 
							
						
 Her testosterone levels are in the normal range for a man, and abnormal for a woman. I'm pretty sure there's plenty of evidence that she has some intersex condition.  | 
						
 A person with XY chromosomes isn't a biological woman if you define "a biological woman" as "a person with XX chromosomes", but why would you do that? Especially in the context of athletic contests, which do not require athletes to be karyotyped before they are allowed to compete. Also, aside from her blood testosterone levels, this is how much medical information you have about her: ZERO.  | 
| 
						She could also just be hyper androgenic without being intersex.  The fact is, WE DON' KNOW.
 I'd we start going down a path of genetic testing for Olympic athletes...wow.  | 
							
						
 Um, because that's the basic definition of male and female? Men have XY chromosomes and have male characteristics and women have XX chromosomes and develop female characteristics. What is your definition if not that?  |
