'Who is our enemy' meme crosses to email

An old philosophy buddy of mine sent me this e-mail message this morning, with the subject “Help me before I get hawkish”:

Despite some fatuous chest-thumping about the greatness of American culture herein, I find this indictment of Arab/Islamist culture hard to argue with, along with the claims about possible Arab responses to the situation. Do the policy prescriptions follow? Of course not. But the author doesn't claim they do, exactly. He invites us to offer an intelligent alternative proposal. Anybody got one?


So a punditblog meme jumps the rails and is now being communicated by email. Is this fairly common?
