No, not a religious calling, per se.
On the other hand, look at where it has gotten us to have teachers with significantly different standards and ideals than the parents of the children they teach.
Teachers have a profound influence on the thinking of our children. They spend more time with our kids than anyone else but us during their formative years, sometimes more.
Can you see a correlation between teachers of lower moral standards and students developing lower moral standards? I can, and I believe there's a clear causation there.
I wish there was a greater concern about the standards and morality of the teachers who spend 6+ hours a day with our children!
Why are you correlating drinking with lower moral standards?
