Biology never said that, and even contradicts your claim. You see, a pioneer in gender ideology named John Muney was a doctor that believed that a man could be a woman and vice versa, he also made gender a biological term instead of relating to grammar, which was the how gender was seen at the time. So one day, these twins were born with a problem that made doctors decide to circumcise them. One of the operations was a success, while the other left one of the twins, whose name was Bruce, without a p**is. Eventually, the parents took Bruce to Dr. Muney and he propose that he turn their infant son into a girl, desperate, his parents let Muney go through with the procedure, and they continued raising Bruce, or as they called him, Brenda, as their daughter, thus we had our first trans person. Bruce never actually felt that he was in fact female though, and as he grew older he tried to reclaim his former self.
He eventually committed suicide.
The gender ideologies that we have today aren't based off of biology, their based off of an incompetent doctor.
I demonstrate that my claim is true through my own experience and those of people I know. The feeling that I get while I sit in church during a sermon, or while I pray, or during worship. When I read about the amazing things written about what Jesus did during his time on Earth. I frequently even hear the stories that pastors tell me about how they interacted with God himself. Even the fact that we live on a planet so fine tuned to the needs of life as we know it is enough to make me believe that there is some higher being that made this world for us.
