I don't know if passion is supposed to be absent from the Buddhist world; my sense is that it all hinges on moderation and self-awareness, that you're neither governed by your passions nor unconsciously repress them. And then, too, there are all sorts of Buddhisms as well; what you get in popular forms like Pure Land sounds to me all about attachment in the same way as evangelical Christianity does. Re. Freud again - funny, I'd just pulled Jessica Benjamin's Bonds of Love off the shelf, as I hadn't looked at it in a while (great book), and she begins with a quote from Civilization and Its Discontents: Where Freud goes with this is to say that repression ends up being necessary in order to prevent the "war of all against all;" Benjamin's idea is that we do have means at our disposal to get past that - in a nutshell, maturing to a fuller understanding of what love is, separating it off from the domination we're subjected to by, e.g., our parents, who are to be both loved and obeyed - a relationship that often enough goes on to colour subsequent relationships. That's where she sees violence entering in - patterns of domination that lie just beneath the surface of consciousness, and where there's not enough awareness of what's going on to allow authentic forgiveness.
