A graphic film is more than a slight hint.
A few blocks from my house, there is a man who faithfully sets up his display of 12-15 giant, full-color images of mutilated fetuses, several times a week. Every time I drive past him, I am grateful I don't have small children in the car.
I would have complained had one of my kids been shown the film at 10 or 11. I would also question the judgement of any teacher who would show such a film to children, and especially without getting the parent's and school administration's permission.
I think it can reasonably be argued that 10 or 11 may be too early to allow public institutions to show such a film. The real question is, depending on what state, shouldn't these films be allowed (even required) to be shown to students that are of abortion-choice age, especially in states where parents do not have to be informed or their consent given?
