While I have nothing to say about your (DH) internal mental states, I think Yoshie is spot on about responsibility and the collective _us_ avoiding, ignoring, denying or downplaying it. Strangely enough, I made the very same point to Yoshie and CB in response to Yoshie's "Bring them home" slogan, in a thread from a while ago.
Yoshie's basic point (as I see it) is so simple that it seems to require no convincing. We as fairly free people have a large set of options to exercise in order to control the activities of our governments and the people who run it. It should be needless to say that this is a general claim which admits to outliers (there may be US liberals or non-liberals who are incapable of acts of protest, or who may already have done all they can, etc).
