Yes you can you can block certain title based on parental ratings without blocking the entire channel...you will have to setup parental controls..
You can always change the channel. If you have minor kids up after you've gone to bed, that is a whole different problem. Kids don't need cable or TV in their room.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
