Your first 5 points are straw man arguments and a complete waste of time.  
1) Hopefully Christian kids are not being “picked on”. Many of the theological views they hold are mocked by teachers and students.  Concentrate on the Beatitudes if you want an insight into Christianity.  
2) They should not be promoting any religion.
3) Schools should teach the skills needed to survive in a very complicated world.  Schools were not designed to provide social welfare. Teachers are not policemen, nurses, psychologists or substitute parents. 
4) Wouldn’t it be easier to teach a transgender student that the world really doesn’t care and isn’t going to play the same games that their teachers play?  
5) Socialism is an economic system that puts community rights over individual rights.  
6) You got this one spot on!
