OK, what you say may be true. What business is it of the school’s?
Praise to the school for actually having some measure of moral, ethical and legal standards for its students' conduct. You shouldn't have to go to a religious school to be taught how to lead a moral and ethical life. Proper learning isn't limited to academics and athletics. Not to mention, any abuse of drugs or alcohol spills over into other aspects of someone's life, including their academic and athletic performance. You can't focus on academics in a vacuum and ignore illegal, abusive behavior that is likely to impact on it. Not to mention behavior that very well may kill your students.
