In the circles of the muslims and their anti-jewish, they speak this kind of message openly. Every time a quranimal goes to the mosque he hears this kind of talk. The importance of this video is that it exposes the full intentions of the muslims without the careful mascaraed that usually accompanies it when they try to speak to the neutral audience.
I think if a normal, neutral person, see what kind of hate and murder are preached in Islam, he would be less inclined to support the "poor Palestinians".
