Klinefelter syndrome (KS), also known as 47,XXY, is a chromosome anomaly where a male has an extra X chromosome.[10] These complications commonly include infertility and small, poorly functioning testicles (if present). These symptoms are often noticed only at puberty, although this is one of the most common chromosomal disorders, occurring in one to two per 1,000 live births. It is named after American endocrinologist Harry Klinefelter, who identified the condition in the 1940s.[4][5][11]
IMO FWIW, thon is more of a woman than Caitlyn Jenner.
You are defining a woman by her genes. So yes, I expect you to have a university degree to be able to make such an authoritative definition.
Several decades ago, the authorities on the subject regarded homosexuality as a mental disorder. Fortunately not all LGBT lay-people deferred to their judgements.
Just like I would expect you to have a degree in physics before making an authoritative definition based on properties of physics.
So I need a degree to say "E=mc2."
Believe it or not, Facebook University isn’t a real university.
