This clip contains the "chickens coming home to roost" sound bite that has been all over the news, especially a certain Faux network.
The problem is that the sermon is anti-war and anti-violence. His point is that "violence begets violence, hatred begets hatred, and terrorism begets terrorism." More to the point, if you pay attention, he was quoting Ambassador Edward Peck.
He was questioning what our response should have been (the video only shows one answer of three -- self-examination of one's own relationship with God).
Here is another sermon that has been taken out of context in the media. This clip contains the "God damn America" clip that is part of a much larger sermon focused on the plight of Black people in America, the unchanging nature of God's truth, and His loving divinity. God has always been a God of love -- and God does not change. His point is that the American government does change, and America has not showed that same unchanging love for Americans of African descent.
I don't agree with the vehemence of his stance, but I support his freedom to say it. And I don't think he is totally wrong. But partial truths can be dangerous.
