For the Bible Tells Me So is a very important documentary about gay children coming out to their parents. It is particularly timely right now, as the country increasingly becomes divisive, and gay teens are desperate enough to commit suicide. There are a lot of great interviews, including Dick Gephardt and his daughter.
I can't imagine how difficult it is to grow up gay in this country. But this film gives an idea of what gay teens have to deal with. It does an excellent job of dissecting the biblical arguments against homosexuality, and gives a lot of interviews with religious people about the subject. Bishop Desmond Tutu is among those interviewed.
I highly recommend the film.
