> I'm as deracinated Westerner as it comes, and yet I'm fairly traditional in this regard. I can think of three acceptable reasons to estrange from parents: sexual abuse, severe physical abuse, and the parents disowning the child. Even the second one leaves a lot of room for reconciliation, since they can't hurt you anymore.

I'm in exactly the same boat. I'm the most hyperindividualist, detached-from-culture, atomized person I know, but my concept of filial (and familial) duty practically makes me an Old Country traditionalist compared to many of my friends.

I don't think my view is as concrete as this, as I don't want to confidently dismiss someone who claims that estrangement is necessary for their mental health. But I'm a little disturbed by the degree to which the current culture diminishes or occasionally entirely dismisses the existence of any familial obligation at all.
