it happened to me once when i try to say that Taylor Swift is born not a female, they said to me that i'm crazy, jealous and other insultYou are perfectly within your rights to disagree with me however, allow me to address everything in your post in order:
1. You're right that everyone's body is different but these skeletal biological markers are what forensic investigators use to determine someone's sex even when the body has been damaged beyond recognition. That's how reliable these markers are. The skeleton allows them to determine the deceased person's sex. Like I said if you test these markers out on strangers in public you'll see the difference between them and those that you see in kpop.
2. I used 99% because I truly believe the number is that high. This is a closed circle of people- notice that a disproportionately large percentage of these celebrities are related, have ties to royal bloodlines and come from very wealthy backgrounds. They use these "survival programs" to convince ordinary people that they actually have a shot at fame when everyone has already been selected. Notice that a lot of those programs have been exposed for being rigged. I wonder why?
3. I agree with you that they mix in some real men and women to keep the masses confused but I believe this number is very, very low. Additionally most people have been brainwashed through the media since childhood and literally cannot tell the difference between men and women on a biological level. They truly believe that these moonbump-wearing men have given birth when that is physically impossible. Do you really think that if anyone came forth claiming that their beloved kpop "idols" are trans that anyone- especially die hard, rabid fans would believe them? Absolutely not. They would call them crazy-and if they had legitimate proof the fans would simply go into denial because the thought of it being true would be too uncomfortable for them to handle.
