Homosexuality

While I definitely believe this school overreacted to the photo, despite what they told the mom, I read an account from a different, secular outlet which added the girl WAS on probation beginning at the first of the school year. The mother allowed as how little Kayla had been caught smoking an e-cigarette on Camus and, on another occasion, had gotten caught ditching school.

From the limited information available, it looks to me like the school was looking for a reason, but even so, expulsion is pretty harsh, even for the Baptists.

It appears from the school's mission statement, philosophy and core values that their entire basis for education and conduct is the ten commandments and other scripture. Is there an 11th commandment, or a chapter and verse in the Bible, that commands "Thou shalt not vape"?

The school is affiliated with the Baptists who do tend to be overly legalistic in their proscriptions.  That said, they only base their behavioral constraints on the Old Testament law because only the OT specifies individual sins.  The New Testament is about Christ fulfilling the OT laws.

This kind of fundamentalism is not uncommon but, in my opinion (for which they did not ask) is, many church congregations carry it too far.  I do get schools, including Christian schools, holding their students accountable to a code of Behavior.  Much like military schools, if you can’t follow the rules, which are known in advance, then go somewhere else.  But by the same token, I also believe our public schools have gone too far the other way, abiding disruptive and even harmful behaviors that should be stopped quickly.  

people send their children to Christian schools for myriad reasons.  This family, in particular, knew the rules well because their older daughter graduated from there.  But I still feel expulsion as the consequence for that “final straw” was over the top.
