They took prayer out of the public schools. 40 years later, students are assaulting teachers & smoking cannabis in class just as the church predicted.

There is zero correlation between these two social issues.

Think of all the countries in the world that never had prayer in schools, countries that haven't had religion in their country for decades or more. Assaulting teachers and smoking cannabis in class is not a problem in any of these places.

Using your logic, it must be the "church" that's causing these problems in the classroom.
