You are completely unhinged from reality, science and human experience. You mention "sound policy and open debate." Nothing is further from the goal of this charade. Don't you think there have always been boys who seem more feminine than the average, and girls who seem more masculine? Why did this suddenly - almost immediately after the Left decided they had won the "gay marriage" issue - become the focus of their efforts?
This is not a "discussion" that the Left would like to have. It is a diktat, completely separated from the normal channels of legislation. Obama and his administration did not use this as an issue is 2012. In fact, they did not make this an issue until after a quick pivot following Obergefell vs Hodges. But they will dictate the terms of this new world, and they will try to make the penalties increasingly severe for those who resist.
The first casualty in this battle is common sense. The whole argument becomes quicksand if you accept their premise, because there is no premise except for the new age push for fairness.
The goal is to completely upend traditional society based on marriage and traditional sexual norms in a Christian society. The Left identified the enemy - Christianity - and is moving to destroy its influence in society. The goal is to force the leftist change through the schools, in the same manner that the Left has always tried to subvert society through its access to young people in education.
In the Left's brave new world, each person can choose whether they are a man or a woman. They don't need any identifying evidence except their feelings, which of course can change day to day. It's not important to separate the sexes in bathrooms or changing rooms or communal showers because one person may feel that they are a certain gender on a certain day. The reason for this separation is not biology, but feelings. But it's also biology because there may be some physical exceptions, as there has always been. Physical gender is not important, but it's so overwhelmingly important that little children should be encouraged to take powerful drugs to change their biology, even if that biology is not as important as their "feelings", Temporary feelings must be accommodated. Ultimately, to buy this contradictory lunacy, you have to throw away the type of logic that allows a society to function. And that is the goal.
A boy in a girls race? That is nuts, plain and simple. This is the intellectual fruit of your nonsense, and is incredibly destructive.
The writer mentioned 6 and 7 year olds were now to be fixed by powerful and dangerous pharmaceuticals in our brave new world. Assuming any adult is depraved enough to participate in this barbarism, I can assure you there will be medical malpractice suits over the hormonal drugging of small children. Juries will throw huge sums of money at the damaged adult as sharp lawyers will focus on the the severe mental and physical damage wrought on a little, innocent child. Testosterone levels are not the only thing that separate men from women and a jury, unlike the utopian "trans" advocates, can be made to understand that easily enough.
The adults involved should actually be prosecuted for child abuse.... and may be if enough sanity returns to society.
