I think a teen's desire to have irresponsible sex has NOTHING whatsoever to do with any teacher, except if they are having sex with the teacher.
It is possible that a teacher could glorify premarital sex. Now, can you connect that to Chippendales? Because that's the issue here.
If even the teacher is going to strip shows, then that must be normal behavior.
RESULT 1) And if it's normal to watch striptease acts, then it's probably normal to have sex outside of marriage.
RESULT 2) Even if they don't instantly make the leap to extramarital sex, you've created the impression in the kid that it is ok to watch sexually charged shows which will stroke their desire for extra-marital sex.
In short, you've created an atmosphere of normalicy around behavior that will lead the kids to failure.
In my mind those were pretty easy dots to connect, but I suppose you still can't see it.
