If you have already seen it, or see it because I have linked to it here, then I recommend that you also watch the speech that Barak Obama made at Cairo University on June 4 earlier this year. You can download it from here (or lower quality video here). It's 54 minutes, but I think it's a significant enough speech in our times that it's worth taking the time to listen.
You will see that much of the video evidence in the first movie is cut, completely out of context*, from the second in such a way as to give a very different message from the one Barak Obama himself was actually giving.
This will hopefully cause you to be sceptical of much of the rest of the short movie because it will be clear that little attempt is being made to present reasoned and fair arguments. Whatever your opinion of Barak Obama (and I myself strongly disagree with him at some points), he should be treated justly. I expect this particularly of Christians who ought to be concerned with truth.
The short movie fails to mention that most of what Barak Obama is quoted as saying is said as a prelude to confronting serious issues in the Islamic world. It leaves out the small yet significant statement in which Barak Obama stands in front of a Muslim audience in a Muslim country and says, "I am a Christian". And if we were better students of history ourselves, we would realise that what he says about history in his speech is true, not a glorification of Islam.
Other parts of the 'evidence' provided is simply laughable. I certainly hope no-one will ever accuse me of being a Christian because I take a tour of Westminster Abbey.
In my opinion, the short movie is political propoganda aimed to turn people against an opponent by using existing fears of Islam. It is misleading, deceptive and slanderous and Christians would do well to disregard it, especially if they wish to maintain a credible witness in the world.
* both the context of the speech and the context in which it was delivered are important considerations.
