I only watched the first third of it, but he seems to be implying that these people did what they did because of a.) their religion and b.) our way of life. I really think both of these are not true, the 9/11 attacks were politically motivated, stemming from decades of interventionist policies by Western nations in the middle east. The hijackers themselves may have been religiously motivated, but the people who orchestrated the plot were politically motivated.
Islamic extremists (I use this word very carefully - most Muslims in the Middle East feel this way, however very few take it to its extreme, deadly conclusion) do not hate our freedom - they hate our policies in their region. Bin Laden is not stupid and uses religion to advance his political goals.
