gbulmash's Journal: Protecting Our Children... From Ideology

I've seen a lot of people shouting about how we have to protect our kids from porn on the Internet. But what about protecting them from ideology? Why is it not okay for someone to show my kid a picture of a bare breast, but it is okay for them to try to convert my child to their religion or political party? So, is ideology as dangerous as porn? If so, shouldn't we be doing as much to protect our kids from ideology as we're doing to protect them from pornography?
