Health, I’ve never come across any NC-17 things on basic cable.
I did specify pornography which is a MAJOR problem in the Orthodox community, whether anyone wants to admit it or not. A person is much more likely to fall into that trap on a computer than a TV.
I still maintain that unfiltered internet = TV.
And yes, you can filter your TV. There are programs out there. Ned Flanders does an excellent job of filtering his TV also 🙂
