Everybody made great observations
I think we all are drawing similar conclusions with slight variances. I wld like to note afew things. Movies and showbiz have always, with some exceptions, remained below the standards of morals of their time to attract people's attention. Mostly, showbiz reflect ills of the society but they instead set lower moral standards for viewers. Over time and after some resitance, younger generation embrace those values, if not completely, but to some extent -- Cycle contiues.
Chinese acupuncture treatment of pain desensitizes nerves that sense and send pain signals to the brain with repeated trauma to it. This treatment kills the nerves ability to sense and feel the pain but pain still exists. I think Queen Victoria or someone familiar with anatomy and phisiology could reflect more and explain it better. Point here is, extended exposure to semi-nude and indecent gestures and postures kills the natural sensitivity towards such ills and they become an acceptable behavior and way of life.
I agree with the argument that some good people fend off negative influence of show-biz and maintain their morals. This section of populace is shrinking at an alarming rate. This notion of people in minority protect their identity with vigor and vigilance is somewhat misleading. Trends in the west are no different from those in Pak. Only 10% to 20% of muslims attend friday prayers and 10% of those (1% of total pop) attend regular prayers. Rest are lost in all sorts of activities.
