Yeah, that's not what my definition of what a geek is.
My definition of a geek, nerd, dork, whatever stupid stereotype you're forcing us to classify ourself into is that it is someone who knows what they like and aren't afraid to show it or admit it.
It might bring some ridicule, but those peoples opinions don't matter because they're going to live shallow, unfulfilled lives fitting into whatever mold they think they need to fit into.
You don't need to guide your children like they have this set path they need to follow, but you do need to help them discover what they like and what they don't. I find that it's the kids whose lives are fully guided by their parents are the ones who ARE influenced by the media and outsiders because they have no say in their life and find a need to rebel.
