You obviously don't have children, or if you do, you don't mind that they're being fed an agenda that will NOT be beneficial to their long-term well being.
I have children, and I instill in them a sense of tolerance, and a love for liberty. They aren't being fed an agenda, I do what so many parents seem to be unwilling to do--Parent. Another example is the fact I have cable, and many violent movies, but they know what they are allowed to watch, and what they are not allowed to, I don't need any liberal or conservative to parent my child, I take care of that.
