OK, I'll take a stab at this. But I'm only gonna pick one category among many, time restraints and all that. TELEVISION. Or maybe more specifically, "creative" programing talents. TV shows, most of them, in the early days were positive reinforcers of values. Then, shows like "Roseanne" came around, which basically celebrated the dysfunctional family. Add in shows like "South Park" where every kind of value is made fun of. Stir in lots of sex, cause that's what sells. Don't get me wrong. I laughed at a lot of those shows, recognizing parody and outrageousness for fun. But constant exposure to most, and especially young people, and the tiny little circuts in people's brains started connecting. Hey, guess what? Nothing is sacred, respect is something to scoff at and rudeness rules AND is funny!
