Weird, in my case it was only in elementary school. High school was not mandatory so the disruptive kids simply didn't go there.
Edit: Oh, just realized that you probably also have middle school. I didn't. It was the same school from age 7 to 15. Education was mandatory till 18 or 16 yo so the school was stuck with all the stupid kids till then.
Don’t underestimate the evangelicals, they will ignore the laws and act like martyrs when punished for it. Then they will run for office as defenders of the constitution and church, get elected, push even more evangelical agenda on everyone, be exposed as homosexuals, retire and live comfortably ever after.
