Shindy, what you say is true. I believe there are two separate diseases called off the derech. In the yeshivishe world, it is caused by either assuring the mutar, or hypocracy. In the modern world it is caused by matiring the assur, and hefkeirus, i.e., free rein of TV, movies, and internet.
This is a symptom of the torn world we live in. There needs to be one standard that we all agree on. I have said countless times, the modern will never give up their movies if you tell then that college is also asur as well and you are supposed to hate the state of Israel. They look at you as being from another planet, and will not listen even when you are right (about movies).
