Thanks for the interesting study you linked.
I don’t necessarily agree with you on your interpretation though. Please understand that I am not a biologist and that my interpretation of the data is focused more on the data itself.
I believe the following excerpt will illustrate my point:
> XX male syndrome is a rare syndrome usually occurs as a sporadic event with a frequency of approximately 1/20,000–1/25,000 individuals. The vast majority, about 90%, has SRY detectable in their cells, the remaining 10% are SRY negative (8), although some research suggest a higher figure that reaches up to 20% of the cases (9).
If we take the middle ground of the estimate of the number of male humans with XX male syndrome we get 1/22,500. Taking the median between the estimate of the number of said men who show no detectable SRY in their cells, we get 15%. Multiplying the average number of men with XX male syndrome by 100 we get 100/2,250,000. We then apply the average percentage of men that show no SRY whatsoever and we find that only 15/2,250,000 men has XX male syndrome AND shows no SRY. This means that only 0.000006667% of the male population has XX male syndrome with no SRY according to the numbers presented by the study.
If we then estimate the world population to be 7.21 billion people with 49% of those people being classified as male, we can then estimate the number of people with XX male syndrome and no SRY. Multiplying 7.21 billion by 0.49 gets us an estimated “male” population of 3,532,900,000. Applying our percentage determined above nets us 23,553.8443. So, according to the study, there are an estimated 23,554 people on this planet with XX male syndrome that show no SRY in their cells. To call this an out lier would be an understatement.
Let’s just agree that at this point, we can objectively determine a person’s biological sex through a number of factors. We cannot, however, determine their gender as it is subjective in nature. Let’s also agree that a person’s biological sex should have no bearing on the way they are treated by society.
