Muslims are attacking us because one of the only allies we have in the ME is Israel.
Now they attack us because we're the big fish they want to take down. They never do it straight up. They attack us at our weak points and through politics. Currently through the UN.
I think you need to focus on something you really have some expertise in.
It tends to bother people when D4A focuses on that particular subject that most interests him.
That aside, I would say that his drivel is only one more attempt at conforming to the simple-minded paradigm much embraced by the non liberal portion of the left called "blowback".
Have you ever read Bin Laden's letters to America? If not, he details within them all the hackneyed laundry lists of grievances that assail western civilization, assail us for supporting Jews against the aggression of Islamists, and offers all the "blowback" rationalizations. Interestingly enough, prominent members of the extreme left like Noam Chomsky agreed, and so simply took all the various themes, dressed them up in florid language to appeal to lefties, and ignored all language about opposing our entire civilization in order to cherrypick the blowback justifications. Much of the left, in turn, has now embraced this rationalization, as the mindless drones now treat it as gospel. D4A may be doing so in an especially clumsy fashion, but he, like most other lock step leftists, has no freaking clue where the originating ideas arose in the first place.
We are hated for who we are. Since we are hated for who we are, then everything we do is wrong. Now, we often do, indeed, indulge in some actions that are wrong (some of the stuff at Gitmo and whathaveyou) ., but this is magnified and treated as the cause rather than the opposition to our way of life being the cause. The truth of the matter is that we can't do anything RIGHT, and so in the long run, what we actually do makes little difference.
The right can produce Jingoists -- "America, love it or leave it", "Kill em all and let God sort it out". The left can produce these reverse jingoists "They wouldn't hate us if we weren't always wrong". Neither has much inclination towards wanting to understand much of anything at all. THeir world is too simple to allow for anything but their narrow little box.
