There are plenty of self-loathing Jews in Israel and this country. Plenty half and quarter Jews served in Hitler's Wehrmacht in WWII, because they didn't want to be seen as Jews, but as "good Germans." If those individuals living in Israel don't support their government trying to save their asses, or the IDF fighting to keep a country for them to live in, then they should leave, and go somewhere else.
I dont think its self loathing
You must recognize different strands of opinion and not call anyone against these actions an anti semite
Most Israelis I think in polls say they want the war to end and for PEACE to ensue!
Go figure...
