Validation of My Parenting Style, Or, Why My Son Wants Breast Implants

I was raised in a pretty liberal Mormon household, as far as television, music, movies, and books were concerned. Although counsel in the Mormon church is to steer clear of rated R movies, I was allowed to watch them, provided my folks had viewed them first, and it was then that I developed a love for slasher flicks--along with classic rock, cerebral and often controversial literature, etc.
I had vowed to be as accomodating to my children's tastes as possible and within reason. I see parents asking questions on Facebook about letting their 10 or 12 year olds watch or read this or that, and I was thinking how I probably would have seen or read whatever they were talking about by the age of seven. And I think it's OK, provided there's parental moderation. I wasn't one of my fellow Mormon classmates who was sneaking out to go see rated-R movies, and I also felt comfortable asking my parents questions about life, sex, violence, etc, instead of searching for answers where I shouldn't. Also, I feel like ANYTHING can be taken out of context and made "bad" with the right material.
Case in point: the most innocent movie in the world, and one of Goob's personal favorites, Toy Story 3. He LOVES this movie, and has watched it...oh...about 900 times.
The other day, after watching it for the 901st time at his grandparents', I noticed he was walking with a swagger, a high pitched voice, and with makeshift boobs and a grin. I cautiously asked him who he was, and he excitedly answered, "BAAARRBBIIEE!!!" He spent an hour of his life being Barbie and wishing he had boobs.
ANYTHING can be taken wrong. Unless it's pornographic or intensely obscene, the key is parental moderation. My son now wants breasts thanks to Pixar. Will I ban the movie? Heck no. But, it did validate my idea that it's less to do sometimes with the material and more how we explain things to our children. Each parent has individual standards, but nothing is OK unless we provide answers to questions and a careful eye. I'd rather moderate than censor.
