Human, these are excellent points, and I agree with your assessment re: the older-yet-still-younger thing.
I remember the mother of one of my friends scolding her once, saying how she (the mom) had to pick out her own mother's casket when she was just 18. She stated that neither my friend, nor any of her older/younger siblings would be capable of that all the way up into their 20's.
Another friend of mine has what she calls an "overgrown teenager" of a sister who is well into her 30's by now and has never moved from home. She occasionally works, then quits or gets fired from a job, and their parents let her hang out in the basement, rent-free.
At the same time, we have neighbors who began letting their 9/10-year old wear provocative clothing (complete with thong underwear and padded, push-up type bras) and makeup at that early age because they saw nothing wrong with it.
I looked at some of the Halloween costumes advertised this year, and was amazed how "sexualized" even the outfits for very young girls have become.
Who is designing these?
Parents can do everything in their power to screen TV programs, etc., but it seems there's no getting away from the negative exposure completely. If they don't see it at home, their friends will likely have access to it, as can also be the case with internet, etc.
If you're willing to build a coccoon, then maybe...but be ready to home-school too, then, because even with no cell phone they'll find kids at school who let them borrow one, and/or may find time to create and maintain MS or FB-type accounts when no one's looking or they're given "free time" in computer lab!
O/T, but I agree about 2.5 Men! It's a shame, as the characters and general storyline always seem decent enough to not "need" to go there, but oh well! I'm obviously not in their targeted demographic, is my guess!
I was watching a "nerd" show earlier tonight, and was disappointed to see that it's also going this route.
They used to stick in stuff "for the adults" that kids who should be too young for certain information would miss (like 3's Company, maybe), but anymore, it's much more direct.
