I'm going to prelude this post by saying I don't have kids and don't plan on having kids for at least 6 more years. Where I am in life right now, my views on rearing kids are as follows.
I think that the parents should be the role models in a childs life. My Mom has always been my role model and always will be. Because of her, I have learned the value of hard work and am always willing to pull my weight. When I have kids, I'm going to raise them like my parents raised me.
My brother and I were allowed to watch about an hour of TV a week, but we didn't care about that because we were out doors playing. Whatever we watched was restricted to certain channels and programs. We were allowed to play video games of the Donkey Kong and Mario varieties. We were home schooled during every summer for 3 hours a day which helped us keep up with our math skills and such.
I had no idea who Christina, Brittney, or anyone was until I was in middle school or later. Growing up, I had no influence of TV role model which I count as a blessing in life.
As for dress, my dad always told me to be the Lamborghini, not the Chevy truck. He said you never see Lamborghini's "advertising their goods", yet everyone knew who they were, so I shouldn't feel the need to either. It has worked for me my whole life. I don't dress in a provocative manner, and never will. Skirts and short dresses make me feel uncomfortable, as do snug tops and low neck lines. My parent s taught me to value myself and how I look so that I could go out into the world and portray myself in a positive manner.
As for exposing your children to multiple relationships... well my father wasn't exactly monogamous in his marriage to my mom, but I did not learn that until later in life when I was mature enough to formulate my own opinions (late teenage years). My mom wanted me to have a positive relationship with my father after they split, and didn't want to taint that with his many exploits.
