I will come off sounding harsh, though I think its worth it. Raising a kid to be open-minded and worldly, does not have to be done by bringing the kid to a burlesque house. We do not expose our kids to drugs, immorality and things that we believe are bad, just for the sake of having open minded kids. I am comparing these examples to TV not because I believe that TV is just as bad. Rather, your post makes it sound that YOU believe that TV is inherently bad for kids (except for the open-mindedness of it).
Either way, I believe that there are many ways to open a kids mind, and the first way starts with the parents being open minded.
