How do you prevent your kids from idolizing Birtney, Miley, Lindsay, Hilary, Simpsons, etc?

Unless you lock them up in their room there is no escape! i think its important to expose them to everything (within limitations of course) that way they can learn the right path themselves. Also having an idol is sometimes a good thing. When i was in high school i used to have problems with low self esteem and confidence and watching the lizzie mcguire show with Hilary Duff actually really inspired me as she got over her 'hurdles' of lacking self confidence it taught me to get over mine. Lindsay and Britney are not so much targeted to kids these days whereas Hilary and Miley still are. I think they both set good examples and its up to your parenting skills to help them distinguish what is "good" and what is "bad". Its important to expose them so they learn their own lessons - hard but the most valuable
