Rodim---Yeah, Japan is wonderfully weird. Ditto India and the United States. (And though they aren't among the developed or "civilized" cultures, the Piraha are pretty weird, too.)
As for vulnerability:
I think context matters. There are moments in life where you'll have to go out on a limb, so to speak, if you want to experience deeper emotions or greater intimacy with someone or something. (For example, think of how vulnerable the average person is during sex!)
Certainly, I hadn't allowed myself to be emotionally open and vulnerable this weekend, I wouldn't have enjoyed "Up" as much as I did. In order to enjoy many books and movies, I have to open myself up to them, and to all they have to offer---the joys, as well as all the sorrows.
On the flip side, there are many times when the vulnerability in question is nothing more than plain old stupidity, or whiny girly-boy weakness. Some folks are *all* soft white underbelly, and it's disgusting.
Anywho, depending on the particulars, I'd tend to call these herbivore boys metrosexuals (as we've discussed), wimps (as Bloodfire mentioned) and/or geeks.
I think "wimps" pretty well gets to the heart of the matter, though.
