Don't be going crazy on me. Children do things all the time and get spanked for it. What would happen if the parent disowned the child.
I'm not so sure the parent/child analogy works here very well. However, the fact that an intelligent and sensitive person like you keeps wanting to use that analogy anyway tells me a lot about the misconceptions that surround this issue.
I guess it depends on whether we are comparing modern political entities or we are comparing civilizations. The US was founded on "Judeo-Christian" values. So who's the child and who's the parent?
The bottom line I take from this is a very helpful reminder that when we act as Israelis or Israel supporters we aren't nearly as strong as when we act as Jews. We became a people at Sinai, not at the Balfour Declaration.
