@JustinMac84 @thejessiekirk I apologize for coming across like that. Please understand that I am coming from the perspective of years of being told that I don't know anything from people who have no advanced biology or genetics experience. It comes from a place of frustration that people use the 'I learned this in high school' as support for - incorrect - statements on biology, i.e. since I learned this in high school and you don't know this basic high school level fact you must be terrible at your job or stupid.
It also comes from a place of frustration of experts and specialists being denigrated because podcaster/youtuber/twitch streamer/etc has convinced them expert = privileged elite who just wants power, money, and control. They have made it a personal identity to not learn facts from experts or challenge their viewpoints.
In broad strokes the high school XY lessons are not technically incorrect, just a combination of oversimplification and scientific knowledge improving over time.* Depending on your generation you may or may not have learned about X and Y non-typical configurations. XX with the SRY (the active part of the Y) being on one or both of the X's, XXY, etc etc. But even if you learned those configurations, most high school curriculum today hasn't caught up with all of the new genes and epigenetic factors we are discovering.
