We have to consider the virus here.
The virus does not mug people, it does not have good or bad intent, and it does not listen to government directives.
It just spreads wherever it gets the chance because, biologically, that is what very infectious viruses do.
We are planning to send our children in together without adequate social distancing, or face masks etc. This will give it the opportunity to infect all of our young people,including the extremely clinically vulnerable. Many of them, especially in secondary school, especially the extremely clinically vulnerable,will get ill, and some of those will die.
This will also transmit infection to the teachers,especially the older and the extremely clinical vulnerable,who will also get ill ,and more of them will die. Likewise family members.
This is called a scientific understanding of the situation. Trust me,I am a doctor 
There is good evidence for transmission in schools from Israel. We are going into the winter months now. The virus likes conditions around 4 degrees C.There is also an issue with travel, especially on buses or trains to secondary schools and colleges. We are also entering flu season.
The virus will not be dissuaded from spread by our political desire for libertarianism, or concerns about children who might be abused etc. The virus will simply do what viruses do, which is infect people. We need to stop it, especially where vulnerable people are concerned. That is the science. It is a very good argument, given the course of the past few months and the mistakes that have been made.
Some posters say they are teachers, and want to dragoon all the kids back. I assume you don´t teach science.
I have absolutely no intention at this time of deregistering. I will bide mt time. Wisely.
