I am an adult. It doesn't matter if I watch them. And, yes. I do. I'm only moments away even from laughing hysterically as the Black Knight gets his arms lopped off and proclaims "It's just a flesh wound."
And I will add this: fake violence does not phase me. It's fake and not real. But real violence, it upsets me. And certain portrayals, such as the events in Schindlers List, because that did happen it's especially upsetting and left me sobbing at several points throughout the movie. But Happy Tree Friends I absolutely love.
What does the question have to do with exposing children to violence?
And the God of Abraham is said to have drown over 99% of all living things on the land. That is vicious, savage, and utterly barbaric.
