I can't add much to TheLady's writeup (except that AFAIK it's all depressingly true), but it should be noted that Israeli Arabs can and do vote and hold public office (for what it's worth; Americans generally seem to assume the contrary, anyhow), and that from what I've seen and read, TheLady's moderate and reasonable view of things is not rare among secular Israelis.

And also that the whole thing has a context, in light of which it may not be more defensible, but is certainly more comprehensible.
