Yes you are right, it is TV and music that is allowing this to become the standard. Parents, teachers, and especially administrators are in a quagmire on this subject. The old damned if you do scenario.
Don't even get me started with the d if you do, d if you don't scenario. It applies to a LOT of stuff nowadays. No matter what some teachers do, there are some vultures flying around waiting to attack--whether it be an intenerant media, certain kids or parents, certain fellow teachers, or the education liberals (those who use liberal methods against education), it can be precarious being a teacher. Luckily, my flexible and low-key way of doing things have so far staved off any real negative stuff happening, but you never know when something is going to happen, especially as a male teacher.
I won't go into all of the scenarios of d if you do and d if you don't. You've probably seen them all anyway. I certainly have seen a lot. Fortunately, the great majority of people I deal with are pretty level-headed.
